Paolo is training for a triathlon, a timed race that combines swimming, biking, and running. Consider the following sentence: Paolo has only 20 hours this week that he can devote to training. Each hour he spends swimming is an hour that he can't spend biking or running. Which basic principle of individual choice do these statements best illustrate?

a. Juanita can use time most efficiently by spending the same amounts of time on swimming, biking, and running.
b. People face trade-offs
c. People usually exploit opportunities to make themselves better off.
d. Juanita has an incentive to spend more time on swimming than on biking or running.

Answers

Answer 1

Answer:

b. People face trade-offs

Explanation:

People usually have different options of a toons that can be taken with their various benefits. These different options available to an individual are called trade offs.

When a particular line of action is taken, the alternative action forgone is called the opportunity cost.

In economics the opportunity cost is also considered along with the actual cost of an activity.

In this scenario Paolo has trade offs of swimming, biking, or running.

However he has only 20 hours this week that he can devote to training. Each hour he spends swimming is an hour that he can't spend biking or running.

So biking and running are the opportunity costs he has to pay for swimming

Option C (Precept............real world) is the right answer.

Explanation:

Laissez-faire economics seems to be a hypothesis that always constrains government interference.

It maintains that perhaps the financial sector was indeed particularly strong since all the current regime was doing was safeguard the freedom of persons. Subsequently, free-market statisticians predicated on the premise of laissez-faire mostly as an approach to sustainable economic success, because while critics disparaged it for helping to promote unfairness.

Required:
a. Determine the amount of the annual lease payments as calculated by the lessor and above situations.
b. Determine the amount lessee would record as a leased asset and a lease liability for above situations.

Answers

Answer:

Answer is explained in the explanation section below.

Explanation:

Data Given:

Situations:

Lease Term years:

1. 12

2. 20

3. 4

Lessor’s rate of return (known by lessee):

1. 11%

2. 9%

3. 12%

Fair value of leased asset:

1. $620,000

2. $1,000,000

3. $205,000

a)  For Situation 1:

Here, lease is a financial agreement between two parties Lesse and Lessor.

So,

Formula for annual lease payments is:

Annual lease payments = Fair value of assets divided by Present value for annuity due.

Here,

we use the following data to calculate the annual payments.

Fair Value of Assets of the leased asset = $620,000

Lease term = 12 years

Lessor's rate of return = 11%

So, the present value of annuity due 12 years at the rate of 11% is 7.2065

Plugging in the values in the formula we get:

Annual lease payments = [tex]\frac{620,000}{7.2065}[/tex]

Annual lease payments = $86,033.44

b)

Formula for the lease ability = Annual rent payment multiply by present value of annuity due.

So,

The annual rent payment is the same that we calculated above.

So,

the lease ability = $86,033.44 x 7.2065

the lease ability = $620,000

For Situation 2:

a)

Annual lease payments = Fair value of assets divided by Present value for annuity due.

we use the following data to calculate the annual payments.

Fair Value of Assets of the leased asset = $1,000,000

Lease term = 20 years

Lessor's rate of return = 10%

So, the present value of annuity due 20 years at the rate of 9% is 9.9501

Annual lease payments = [tex]\frac{1,000,000}{9.9501}[/tex]

Annual lease payments = $100,501.35

b)

Formula for the lease ability = Annual rent payment multiply by present value of annuity due.

the lease ability = $100,501.35 x 9.9501

the lease ability = $1,000,000

For Situation 3:

a)

Annual lease payments = Fair value of assets divided by Present value for annuity due.

we use the following data to calculate the annual payments.

Fair Value of Assets of the leased asset = $205,000

Lease term = 4 years

Lessor's rate of return = 12%

So, the present value of annuity due 4 years at the rate of 12% is 3.4081

Annual lease payments = [tex]\frac{205,000}{3.4801}[/tex]

Annual lease payments = $60,261.66

b)

Formula for the lease ability = Annual rent payment multiply by present value of annuity due.

the lease ability = $60,261.66 x 3.4801

the lease ability = $205,000

Discuss the differences between the short run equilibrium and long run equilibrium from the perspective of producers and from the perspective of consumers. Why do you think it is important for managers to understand the mechanics of supply and demand in the short run and in the long run? Give an example of a company whose business was either helped or hurt by changes in supply or demand in the markets in which they were competing

Answers

Answer:

In the long-run, the economy tends to favor consumers more than it favors producers.

Explanation:

This is because, in competitive market structures, firms earn economic profit only in the short-run, but in the long-run, this economic profit either disappears, or decreases substantially, because the structure of the market itself provides incentive for a dynamic flux of firms in and out of the industry, and economic profit moves along that flux: it goes up when the number of firm in the industry goes down, and it goes down when the number of firms in the industry goes up.

Managers should understand these dynamics in order to be able to forecast trends and act accordingly, mainly by developing corporate strategy that tackle the forecasted scenarios.

Finally, an example of a business affected by a fall in demand is airline companies. The airline market is very competitive even if it is dominated by a few firms due to very high barriers to entry and exit. Airline companies are constantly pressured to offer lower prices, while costs do not necessarily fall at the same rate. The recent demand shock due to the current pandemic has left most airlines in a dire condition, using up past reserves to operate, and frequently in need of government assistance.

If the firm has 200,000 common shares outstanding, zero preferred shares, and debt with a market value of $10,000,000 what would be the value of each share

Answers

The complete question is:

Acme Medical Corp. is expecting the cash flows from 2018-2022 in the table below. After 2022 it is expecting growth in cash flow at an annual rate of 3%. The firm has determined that its weighted average cost of capital (discount rate) is 7%. Using the table below calculate the following:

Year Cash flow

2018 500,000

2019 550,000

2020 620,000

2021 700,000

2022 800,00

Answer: Share value = $36.23

Explanation:

First of all we need to calculate the present value of future cash flows of the company

Weighted average cost of capital is given as 7% so discounts will be made against 1.07

Present value = 500,000/(1+0.07) + 550,000/(1+0.07)^2 + 620,000/(1+0.07)^3 +700,000 /(1+0.07)^4 + 800,000/(1+0.07)^5 + [(824,000/0.04)/(0.07)^5]

Present value =$17,245,716.59

Share value will be present value of future cash flows minus market value of the company, and divided by number of shares

Share value = (17,245,716.59 - 10,000,000) ÷ 200,000

Share value = $7,245,716.59 ÷ 200,000

Share value = $36.23

a. A decrease in aggregate demand will only lead to a temporary departure from full employment output. Since prices and wages are flexible, the economy will automatically adjust to full employment in the long run.
b. The velocity of money, while not constant, is predictable.

Answers

Answer:

a. Classical theory

b. Monetarist school.

Explanation:

Classical theory assumes that the fall in aggregate demand will create temporary affect on employment and ;later in the long run economy will adjust itself and will be at full employment automatically. Keynesian theory believes that demand is the factor which drives the economy. If the economy is at recession then efforts should be made to increase demand which will turn the economy growth upright.

BJ Corporation is a cash-basis business. BJ signed a six-month, 12% note payable of $5,000 on October 1st, 2022. By recording the interest expense related to the note only when it is paid on April 1st, 2023, BJ will understate expenses by ________ on its year-end financial statements on December 31st, 2022. A : $5,600 B : $300 C : $0 D : $150

Answers

Answer:

D : $150

Explanation:

The computation of the interest expense understated is given below:

= Note payable amount × rate of months × given months ÷ number of months

= $5,000 × 0.12 × 3 months ÷ 12 month

= $150

Hence, the interest expense that would be understate by $150

Therefore the correct option is d.

On January 1, 1980, Jack deposited 1,000 into Bank X to earn interest at the rate of j per annum compounded semi-annually. On January 1, 1985, he transferred his account to Bank Y to earn interest at the rate of k per annum compounded quarterly. On January 1, 1988, the balance at Bank Y is 1,990.76. If Jack could have earned interest at the rate of k per annum compounded quarterly from January 1, 1980 through January 1, 1988, his balance would have been 2,203.76. Calculate the ratio kjkj.

Answers

Answer:

Ratio k/j is 1.25.

Explanation:

Note: There is a slight typographical error in the requirement. The requirement is therefore correctly stated as follows:

Calculate the ratio k/j.

The explanation of the answer is given as follows:

This can be calculated using the following formula:

A = P (1 + (r / m))^(tm) ……………………….. (1)

Where;

A = Balance

P = Amount invested

r = annual interest rate

t = number of years

m = number of compounding

From the question, there are 2 alternatives as follows:

Alternative A

For Bank X

P1 = $1,000

r1 = j

t1 = number of years from 1980 to 1985 = 5

m1 = semiannual = 2

A1 = Amount transferred to Bank Y = P2 = ?

For Bank Y

P2 = ?

r2 = k

t2 = number of years from 1985 to 1988 = 3

m2 = quarterly = 4

A2 = $1,990.76

Alternative B

For Bank Y only

P3 = $1,000

r3 = k

t3 = number of years from 1980 to 1988 = 8

m3 = quarterly = 4

A3 = $2,203.76

For Bank Y in alternative B, we can use equation (1) and solve for k as follows:

2,203.76 = 1000 * (1 + (k / 4))^(8 * 4)

2,203.76 / 1000 = (1 + (k / 4))^32

2.20376 = (1 + (k / 4))^32

2.20376^(1/32) = 1 + (k / 4)

1.02500004450895 = 1 + (k / 4)

1.02500004450895 - 1 = k / 4

0.02500004450895 = k / 4

k = 0.02500004450895 * 4

k = 0.10

For Bank Y in alternative A, we can use r2 = k = 0.10. Therefore, using equation (1) for Bank Y in alternative A, we can solve for P2 as follows:

1,990.76 = P2 * (1 + (0.10 / 4))^(3 * 4)

1,990.76 = P2 * 1.3448888242463

P2 = 1,990.76 / 1.3448888242463

P2 = $1,480.24

From Bank X in alternative A, we now have A1 = P2 = $1,480.24. For Bank X in alternative A, we can now use equation (1) and solve for j as follows:

1,480.24 = 1,000 (1 + (j / 2))^(5 * 2)

1,480.24 / 1,000 =(1 + (j / 2))^10

1.480.24 =(1 + (j / 2))^10

1.480.24^(1 / 10) = 1 + (j / 2)

1.03999969894693 - 1 = j / 2

0.03999969894693 = j / 2

j = 0.03999969894693 * 2

j = 0.08

Since k = 0.10 and j = 0.08, ratio k/j can be calculated as follows:

Ratio k/j = 0.10 / 0.08

Ratio k/j = 1.25

n order to build a new warehouse facility, the regional distributor for Valco Multiposition Valves borrowed $1.6 million at 12% per year interest. If the company repaid the loan in a lump sum amount after 2 years, what was the amount of the payment

Answers

Answer:

the amount of the payment is $2,007,040

Explanation:

The computation of the amount of the payment is as follows:

= Borrowed amount × (1 + rate of interest)^number of years

= $1,600,000 × (1 + 0.12)^2

= $2,007,040

We simply applied the future value formula to determine the amount of the payment

Hence, the amount of the payment is $2,007,040
