Expert Solution

Suppose a bakery faces a market price of $4 per loaf of bread. Suppose the optimal quantity (Q*) of bread is 2,500 and at this quantity the average total cost (ATC) is $2.5 per loaf. What would be the short-run profit of the bakery?

a. $10,000.

b. $6,250.

c. $3,750.

Right answer. Average profit per unit = 4 - 2.5 = 1.5. Total profit = 2500 * 1.5 = 3750

d. $2,500.

Suppose a pizzeria faces a market price of $20 for a large pizza. Suppose the optimal quantity (Q*) of pizzas is 1,500. What would the average total cost have to be at Q* in order for the pizzeria to break-even in the short-run?

a. $75.

b. $25.

c. $20.

Break even is where the profit is zero. So average total cost will be equal to price.

d. $17.5.

What is the long-run effect when new firms enter into a perfectly competitive industry?

a. They drive up the long-run equilibrium price.

b. They reduce the equilibrium quantity.

c. They increase each individual firm's demand.

d. They eliminate economic profits. Right answer - they drive price down resulting in elimination of (super-normal) profits)

Which of the following happens when firms in an industry are incurring losses?

a. New firms will be drawn into the industry, thereby driving down the average cost of production.

b. New firms will be drawn into the industry, thereby raising the price.

c. Some firms will leave the industry in the long run.

Right answer. Some firms leaving will drive the price up eliminating the losses for the remaining firms.

d. All firms will leave the industry in the long run.

Bakery A sells bread for $2 per loaf that costs $0.80 per loaf to make. Bakery A gives a 75% discount for its bread at the end of the day. Demand for the bread is normally distributed with a mean of 300 and a standard deviation of 30. What order quantity maximizes expected profit for Bakery A? a) 324.00 b) 300.17 c) 325.25

Question 1 Suppose that the price of bread increases from $1/loaf to $2/loaf, resulting in the quantity demanded of bread to decrease from 200 loaves to 160 loaves. What is the arc elasticity of demand for bread? Is bread elastic or inelastic? Why? Is demand for bread elastic or inelastic over this price range? (20 points) Question 2 If a firm wants to increase revenue on its product. Clearly explain why the owner needs to know whether their product is...

Suppose that a perfectly competitive firm faces a market price of $5 per unit, and at this price, the upward-sloping portion of the firm's marginal cost curve crosses its marginal revenue curve at an output level of 1,500 units. If the firm produces 1,500 units, its average variable costs equal $5.50 per unit, and its average fixed costs equal $0.50 per unit. What is the firm's profit-maximizing (or loss-minimizing) output level? nothing. (Enter your response as a whole number long dash—...

The number of loaves of bread sold per day by an organic bakery over the past...

The number of loaves of bread sold per day by an organic bakery over the past five years can be treated as a random variable that is normally distributed. This distribution has a mean of 77.5 and a standard deviation of 14.4 loaves. Suppose a random sample of 36 days has been selected. Determine the probability that the average number of loaves sold in the sample of days exceeds 80 loaves. First find the standard error of the mean. Now...

Suppose Mary and Tom both work at a bakery making muffins and bread. Both Tom and Mary have two hours to work. It takes Mary 2 minutes to make a loaf of bread and 10 minutes to make a muffin. John takes 5 minutes to make a loaf of bread and 15 minutes to make a muffin. a) Draw the joint Production Possiblity Frontier for bread and muffins. Be sure to label the x-intercept, the y intercept, the slope along...

Alex owns and operates a bakery. The bakery sells 3,000 cookies per month at a price of $2 each and 400 cakes per month at a price of $10 each. It costs Alex $1,500 per month to rent the space in which their bakery operates, $500 per month for utilities and $2,000 per month for the baking ingredients they use to make the cookies. Alex's previous job as a baker for a large restaurant paid an income of $3,000 per...

4. Suppose a monopolist faces two markets with the following demand curves: Market 1: ?1(?1) = 400 − 2?1 Market 2: ?2(?2) = 1000 − 4?2 Let the marginal cost be $20 per unit in both markets. If the monopolist can price discriminate, what should be ?1 and ?2 to maximize the monopolist’s profit?
