The price of a large pizza decreased from $18.00 to $14.00. As a result, the quantity demanded of skateboards increased from 330

natta225 [31]

Answer:

a. The percentage change in pizza prices is -25.00%.

b. The percentage change in pizza prices is 5.88%.

c. The cross elasticity of demand for pizza and skateboards is -23.53%.

We follow these steps to arrive at the answer.

<h3>a. Percentage change in price of pizza</h3>

The percentage change in price of pizza using the midpoint formula is:

$percentage change in price = ({\frac{P_{2} - P_{1}}{Average price})*100$

$Average Price = \frac{P_{2} + P_{1}}{2}$

In this question, P₁ is $18 and P₂ is $14

Substituting the values in the formula above we get,

$Average Price = \frac{14 + 18}{2}$

$Average Price = \frac{32}{2}$

$Average Price = 16$

$percentage change in price = (\frac{14 - 18}{16})* 100$

$percentage change in price = (\frac{-4}{16}) * 100$

$percentage change in price = -25$ %

<h3>b. Percentage change in quantity demanded of skateboards</h3>

The percentage change in quantity of skateboards using the midpoint formula is:

$percentage change in quantity = (\frac{Q_{2} - Q_{1}}{Average Quantity})*100$

In this question, Q₁ is 330 and Q₂ is 350

Substituting the values in the formula above we get,

$Average quantity = \frac{Q_{2} + Q_{1}}{2}$

$Average quantity = \frac{350 + 330}{2}$

$Average quantity = 340$

$percentage change in quantity = (\frac{350 - 330}{340})*100$

$percentage change in quantity = (\frac{20}{340})*100$

$percentage change in quantity = 5.8823529$ %

<h3>c. Cross Elasticity of demand of skateboards and pizza</h3>

We calculate the cross elasticity of demand as follows:

$Cross Elasticity Demand = \frac{percentage change in quantity of skateboards}{percentage change in price of pizza}$

$Cross Elasticity Demand = \frac{0.058823529}{-0.25}$

$Cross Elasticity Demand = -0.235294118$

$Cross Elasticity Demand = -23.53$ %

Madeline quits her job, at which she was earning $20,000 per year. She then takes $50,000 out of savings, on which she was earni

Alenkinab [10]

Answer:

A. Madeline's accounting cost is $75,000

B. Madeline's economic cost is $100,000

C. Madeline's accounting profit is $75,000

D. Madeline's economic profit is is $50,000

Explanation:

A. To calculate Madeline's accounting cost we would have to make the following calculation:

Madeline's accounting cost=cost of supplies+rent+labour costs

Madeline's accounting cost=$50,000+$10,000+$15,000

Madeline's accounting cost=$75,000

B. To calculate Madeline's economic cost we would have to make the following calculation:

Madeline's economic cost=explicit cost+implicit cost

=$75,000+opportunity cost

=$75,000+0.10*$50,000+earning job

=$75,000+$5,000+$20,000

=$100,000

C. To calculate Madeline's accounting profit we would have to make the following calculation:

Madeline's accounting profit=revenue-accounting cost

=$150,000-$75,000

=$75,000

D. To calculate Madeline's economic profit we would have to make the following calculation:

Madeline's economic profit=revenue-economic profits

=$150,000-$100,000

=$50,000

Advertising expenses are a significant component of the cost of goods sold. Listed below is a frequency distribution showing the

Sonbull [250]

Answer:

Mean = 47

Median = 47.38

Standard Deviation = 12.73

Explanation:

Note: You wrote " 40 manufacturing companies, but the total number of companies you actually listed is 75, definitely you meant 75.

Let y represent the range of advertising expenditure, f represent the number of companies, x represent the midpoint of the range of advertising expenditure.

y f x fx fx²

$20 to under $30 9 25 225 5625

$30 to under $40 13 35 455 15925

$40 to under $50 21 45 945 42525

$50 to under $60 18 55 990 54450

$60 to under $70 14 65 910 59150

n = 75 $\sum fx = 3525$

$\sum fx^2 = 177675$

Mean, $\bar{X} = \frac{\sum fx}{n}$

$\bar{X} = \frac{3525}{75} \\\bar{X} = 47$

Standard Deviation:

$SD = \sqrt{\frac{n \sum fx^2 - (\sum fx)^2}{n(n-1)} } \\SD = \sqrt{\frac{(75*177675) - (3525)^2}{75(75-1)} }\\SD = 12.73$

Median:

Get the cumulative frequencies(cf)

y f cf

$20 to under $30 9 9

$30 to under $40 13 22

$40 to under $50 21 43

$50 to under $60 18 61

$60 to under $70 14 75

N = 75

Median = Size of (N/2)th item

Median = Size of (75/2)th item

Median = Size of (37.5)th item

The median class = 40 to under 50

Lower limit, L₁ = 40

Cumulative frequency, cf = 22

f = 21

Class Width, h = 10

Median = $L_1 + \frac{ (N/2) - cf}{f} * h\\$

Median = $40 + \frac{ (75/2) - 22}{21} * 10\\$

Median = 47.38
