There are 20 owners for McJellies, Inc. None of those owners are personally financially liable for the company. What type of business is this?
- Sole Proprietorship
- Corporation
- Partnership

Answers

Answer:

- Corporation

Explanation:

At least two people are required to form a corporation. The owners of a corporation are treated as separate entities from the business. The owners, also known as shareholders, enjoy limited liabilities to the debts of the corporation. In case of a liquidation, they cannot lose more than their capital contribution.

A sole proprietorship is owned by one person, but a partnership requires at least two people to form. The owners of sole proprietorships and partnerships have unlimited liabilities to the debts of their businesses. Should the businesses fail in meeting their obligations, owners' personal assets can be used to settle the outstanding debts.

Jane Spring maintained this record of vehicle expenses for last year: gas, $845.96; oil, lube, miscellaneous, $68.85; insurance, $418.50; and license, $35.00. She drove 8,280 miles last year. Her 2-year-old vehicle cost $19,860.00 new and is now worth $11,860.00. a. What was her depreciation? b. What were her total variable costs?

asap pls I need it

Answers

Answer:

Explanation:

a. What was her depreciation?

Since her 2-year-old vehicle cost $19,860.00 new and is now worth $11,860.00. The depreciation will be:

= $19860 - $11860

Accumulated depreciation = $8000

The depreciation for each year will be,: = $8000/2 = $4000

b. What were her total variable costs?

This will be the addition of the gas, and the oil and miscellaneous which will be:

= $845.96 + $68.85

= $914.81

We should note that the insurance and license are fixed cost.

A firm sells 2000 units at £500 each. If fixed costs are £50,000 and variable costs are £100 per unit, calculate the total costs

Answers

Answer: £ 250,000

Explanation:

Given: Fixed costs = £50,000

Number of units=2000

Variable cost per unit = £100

Since Total variable cost = (Number of units) x (Variable cost per unit)

=2000 x ( £100)

=  £200,000

We know that,

Total cost = Total fixed cost +Total Variable cost

= £ (50,000 + 200,000)

= £ 250,000

Hence,  the total costs =  £ 250,000

How could the respective roles of these two labour organizations influence actions by other parties to address the concerns raised by affected Tim Horton's employees?

Answers

The correct answer to this open question is the following.

Unfortunately, you did not include the name of the two labor organizations. There is no further context, reference, text, or article.

However, trying to help you we can comment on the following.

Probably, you are referring to the Ontario Federation of Labor (OFL) and the Ontario Public ServiceEmployees Union (OPSEU).

If that is the case, we say that these two labor organizations have a major role in supporting the employees of Tim Horton's branches, after the response, they have taken in Ontario regarding the increase of the minimum wage in that Canadian province.

The power of these labor organizations created awareness of the employee's situation when different media channels covered the news about the demonstrations. This coverage was nationwide, alerting all Canadians about the situation in some branches of this famous and cherished Canadian fast-food restaurant.

This situation does not only grab the attention of public opinion but from the government and political parties that can get into the discussion, affecting the public image and reputation of Tim Horton.

It is easier to increase the supply of chocolate than the supply of cocoa beans. Do you agree with this statement? Give reasons for your answer.

Answers

I agree.

On average cocoa trees need around 4-5 years before they eventually bear fruit and can produce cocoa beans. On the other hand, producing chocolates from those cocoa beans need around 5-8 days.

compared to producing chocolate, producing cocoa beans require more long-term planning and investment, which make it harder to suddenly increase the supply of the beans.

How do stocks and bonds differ?

A. Stocks are low risk while bonds are high risk.
B. Stocks may help you protect your money from inflation while bonds may be more susceptible to losing their value over time due to inflation.
C. Stocks are loans you give out to corporations and get paid back with interest; bonds are shares of a company that you own.
D. Stocks are good for income while bonds are good for long-term growth.

Answers

Answer:

D. Stocks are good for income while bonds are good for long-term growth.

Explanation:

A Stock is the smallest unit of a corporation. A stockholder is one of the owners of a corporation. Should the corporation makes profits, stockholders are entitled to dividends. Stocks are traded in the exchange markets. When the market or the corporation is doing well, stock price increases representing a capital gain to the shareholders.

Bonds are debts instruments that governments and corporates use to raise capital. They present long term investment opportunities to investors. Bonds offer regular and fixed interest payments to investors until maturity.

Stocks are riskier than bonds. Stock prices experience volatility as they trade every day. Their prices are likely to rise when the markets are favorable, which means profits to investors. Bonds are less risky and offer stable incomes for the long term.

Identify and explain one advantage and one disadvantage to BMW if the government increased value added tax

Answers

Answer:

The advantage for BMW is that an increase in value added tax will also affect BMW cars. This means that BMW will be more expensive, making it likely to for BMW earn more revenue, and thus, for its stockholders to earn more profit.

However, the disadvantage is exactly the same, just the other way around: the VAT increase would also affect prices for many parts, supplements, and other goods and services that BMW acquires to make cars. This in turn will also raise production costs, making higher selling prices not only a possibility, but likely a necessity in order to maintain profit margins.

C.

D.
using deposits made by customers to make loans

Answers

Answer:

D

Explanation:

One primary role of banks in the United States is to use deposits made by customers to make loans. The correct option is d.

Banks play a significant role in the economy by giving people and businesses access to the capital they require for a variety of objectives by leveraging customer deposits to create loans. It's crucial to remember, though, that banks must strike a balance between lending and keeping enough reserves on hand to meet their obligations as well as regulatory requirements.

Deposits are accepted by banks from people, companies, and other organizations. These deposits may take the form of certificates of deposit (CDs), checking accounts, savings accounts, or other forms of accounts. Banks make loans using a part of the deposits they receive. The banking system that uses fractional reserves is known as such. Banks are permitted to lend out a specific portion of client deposits while holding a small portion as reserves, as opposed to maintaining all of such deposits in their vaults.

D. It is increased by the sale amount.

Answers

Answer:

Which of the following is likely to require the most education?
A.
Hand packer
B.
Warehouse stocker
C.
Curator
D.
Restaurant dishwasher

Answers

Answer:

A. Hand packer

Explanation:

Bachelors degree refers to an academic degree (certificate) awarded to a student by a tertiary institution (university or college) after the completion of his or her educational programme.

Additionally, a certification can be defined as a recognition given for completing a course of study or passing an examination. This is to certify that the individual is a professional in that course of study. Some examples are CCNA, Comptia A+, HSE I and II.

A hand packer refers to an individual (employee) who is saddled with the responsibility of packing and/or packaging varieties of finished goods (products) in an assembly line.

Basically, hand pickers are employed to pick and package finished goods into their respective containers so as to get them ready for distribution to the consumers.

Hence, hand packer is most likely to require the most education when compared with a warehouse stocker, curator, and restaurant dishwasher.

Answer:

Curator

Explanation:

7.4% of hand packers have a bachelor's degree.

11.4% of warehouse stockers have a bachelor's degree.

While most curator positions require a master's degree in art history or museology, smaller galleries may only require a bachelor's degree in art or art history. Larger organizations typically require a master's or doctorate in art or art history.

There are no education requirements for most dishwasher positions but some employers prefer dishwashers have a high school diploma or GED.
