Jason decides to sell his band's CD. It required an investment of $3349 for computer hardware and it will cost $3.65 for materials for each disk. If each CD sells for $13.50, how
many must he sell to break even?
196 CDs
340 CDs
339 CDs
195 CDs
Answer:
340 CDs
Step-by-step explanation:
To answer this question, we're dealing with three functions for one problem, namely the revenue function, the cost function, and the profit function.
The revenue function is R(q) = pq, where p is the price of a certain good and q is the quantity sold.
The cost function is C(q) = variable cost + fixed cost, where variable costs changes depending on the quantity of goods produced and fixed cost is a one-time cost for the producer (e.g., an investment, rent, etc.).
The profit function is P(q) = R(q) - C(q) and is simply the cost function subtracted from the revenue function.
The "break-even point" is the point at which profit = $0 and the point at which cost = revenue.
From the problem, we see that Jason invested $3349 (once) for his CDs and each disk requires $3.65 for the materials so our cost function is C(q) = 3.65q + 3349
Furthermore, we see that each disks sells for $13.50, so our revenue function is R(q) = 13.5q
Our profit function then is P(q) = 13.5q - (3.65q + 3349) = 13.5q - 3.65q - 3349 = 9.85q - 3349.
Thus, to find the break-even point, we set profit = 0 and solve for q:
[tex]0=9.85q-3349\\3349=9.85q\\340=q[/tex]
Determine the largest power of 10 that is a factor of the following numbers (equivalently, the number of terminal 0's, using ordinary base 10 representation):(a) 50!.
(b) 1000!.
The largest power of 10 that is a factor of 1000! is 5^249, or 10^249.
(a) To find the largest power of 10 that is a factor of 50!, we need to count the number of factors of 5 in 50! since each factor of 5 contributes at least one factor of 10.
There are 10 multiples of 5 in 50!, namely 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50. Each of these contributes one factor of 5. There are also 2 multiples of 25 (25 and 50), each of which contributes an additional factor of 5. Therefore, the total number of factors of 5 in 50! is 10 + 2 = 12.
Since each factor of 10 contains one factor of 5 and one factor of 2, we also need to count the number of factors of 2. It is clear that there are more factors of 2 than factors of 5, so we only need to count the factors of 5. Therefore, the largest power of 10 that is a factor of 50! is 5^12, or 10^12.
(b) To find the largest power of 10 that is a factor of 1000!, we follow the same reasoning as in part (a). The number of factors of 5 in 1000! is:
⌊1000/5⌋ + ⌊1000/25⌋ + ⌊1000/125⌋ + ⌊1000/625⌋ = 200 + 40 + 8 + 1 = 249

on its December 31 balance sheet.
Current Assets:
Accounts receivable $120,000
Less: Allowance for doubtful accounts $???
Answer:
To determine the balance in the Allowance for Doubtful Accounts on December 31, we first need to estimate the bad debts based on the credit sales.
Bad debts = 2% of credit sales = 2% * $400,000 = $8,000
The balance in the Allowance for Doubtful Accounts would then be equal to the estimated bad debts, which is $8,000.
Therefore, the Accounts Receivable and the Allowance for Doubtful Accounts would appear on the December 31 balance sheet as follows:
Current Assets:
Accounts receivable $120,000
Less: Allowance for doubtful accounts $8,000

When the price of almond milk is $3 per half gallon the quantity demanded of
oat milk is 20,000 half gallons. When the price of almond milk is $5 per half
gallon the quantity demanded of oat milk is 30,000.
Calculate the cross-price elasticity of demand for almond milk and oat milk.
Based on your calculation, what type of goods are almond milk and oat milk?
Answer:
Step-by-step explanation:
The cross-price elasticity of demand measures the responsiveness of the quantity demanded of one good to a change in the price of another good. In other words, it shows how the demand for one good changes in response to changes in the price of another good. The cross-price elasticity of demand is a useful concept for understanding the relationship between two goods and can provide valuable information for firms in making pricing and marketing decisions.
The formula for cross-price elasticity of demand is as follows:
Cross-price elasticity of demand = (Percentage change in quantity demanded of good A) / (Percentage change in price of good B)
In this case, we are calculating the cross-price elasticity of demand between almond milk and oat milk. To do this, we first need to calculate the percentage change in quantity demanded of oat milk and the percentage change in price of almond milk.
Percentage change in quantity demanded of oat milk = (30,000 - 20,000) / 20,000 = 0.5
Percentage change in price of almond milk = ($5 - $3) / $3 = 0.67
Next, we use these values to calculate the cross-price elasticity of demand:
Cross-price elasticity of demand = 0.5 / 0.67 = 0.74
A positive cross-price elasticity of demand indicates that the two goods are substitutes. This means that as the price of one good increases, the demand for the other good increases. A cross-price elasticity of demand between 0 and 1 indicates that the two goods are weak substitutes. In this case, a cross-price elasticity of demand of 0.74 suggests that almond milk and oat milk are weak substitutes. This means that if the price of almond milk were to increase, the demand for oat milk would increase to some extent, but not by a significant amount.
In conclusion, the cross-price elasticity of demand provides valuable information for firms in making pricing and marketing decisions. A positive cross-price elasticity of demand indicates that two goods are substitutes, while a cross-price elasticity of demand between 0 and 1 suggests that they are weak substitutes.

What is an equation of a circle?
A circle is the collection of all points on a plane at a specific radius from a specific point (called the center.) The diameter of a circle is the length of a line that connects two locations on the circle and passes through its center. Assume that a point's coordinates on the shown circle are (x,y). The radius is r, and the center is at (h,k).
Here according to the graph, the center of the circle is (2,-1), and the radius of the circle = 2+2=4 unit.
Now using the circle equation then
(x -p)² + (y-q)² = r²
Where p = 2 , q = -1 and r = 4 then
(x -2)² + (y+1)² = 4²
(x -2)² + (y+1)² = 16
Hence, the equation of the circle is (x -2)² + (y+1)² = 16.

As a technical engineer, you must calculate the elevation of a Point marked on a topographic map. The distance between the 420-foot and 440-foot contour lines is 0.5 inches, and the marked point between them is 0.2 inches from the 420-foot contour. What is the elevation, in feet, of the marked point?
A.100
B.424
C.428
D.430
E432
Answer:
The correct answer is C, 428 feet.
To calculate the elevation of the marked point, we need to interpolate between the two contour lines. The difference in elevation between the two contour lines is 20 feet (440 - 420 = 20). And since the distance between the two contour lines is 0.5 inches, each 0.1 inch increment represents a 4-foot change in elevation (20 feet ÷ 0.5 inches = 40 feet per inch ÷ 10 = 4 feet per 0.1 inch).
Since the marked point is 0.2 inches from the 420-foot contour, the elevation of the marked point can be calculated by adding 8 feet (4 feet x 0.2 inches) to the 420-foot contour line: 420 + 8 = 428 feet.
HelpThe ratio of the perimeters of two similar quadrilaterals is 2:4. What is the ratio of their areas? PLLLLLLLLLLSSSSSSss
a.1:2
b. 4.8
c. 2:4
d. 4:16
e. 5:3
The ratio of the areas of the quadrilaterals is 1:2. Option A
What is the ratio of the perimeter?Let's assume that the two similar quadrilaterals have side lengths of x and 2x, respectively. The ratio of their perimeters is then 2x + 2x + 2x + 2x = 8x : 2 * (2x + 2x + 2x + 2x) = 4 * 8x = 32x. The ratio of the perimeters is 2:4, so we can write the equation:
8x/32x = 2/4
Solving for x, we find that x = 4.
So the ratio of the areas of the two similar quadrilaterals is (x^2)/(2x)^2 = (4^2)/(2 * 4^2) = 16/32 = 1/2.
Therefore, the ratio of the areas of the two similar quadrilaterals is 1:2.

An electrician charges a set fee of $100 for every house call and then charges an
additional $60 per hour. Make a table of values and then write an equation for C, in
terms of t, representing the total cost of the electrician's services if the electrician
spends t hours at the house working.
Answer:
C = 60t + 100
Step-by-step explanation:
our flat fee is 100 dollars, meaning you're charged straight up $100, and then for each hour the electrician works, you're charged another $60
this means that 100 stays constant, while the amount of times you multiply 60 changes based on the amount of hours the electrician works
therefore, our equation will be C = 60t + 100, where C represents the total cost while t represents the hours the electrician works
for our table, we can use the equation we just found to make one
the easiest and most reasonable numbers will be 1, 2, 3, 4, and 5, because it's unreasonable to charge a proportional amount for something such as 1.2948 hours
using the equation, we plug 1, 2, 3, 4, and 5 into C = 60t+100 to find C for t
C = 160, 220, 280, 340, 400
T = 1, 2, 3, 4, 5
