The figure depicts the demand curve of a firm producing cars, together with its marginal cost, average cost, and isoprofit curves. Based on this figure, which of the following statements are correct? 8,000 Price, Marginal cost ($) 0 E Quantity of cars, Q At A, the firm makes positive profits. The firm makes the same profit at B and D. O Profit margin is the same at B and D. O The slope of the isoprofit is zero at D. MC Isoprofit A Isoprofit B AC 100
The curves show the marginal cost (MC), average variable cost (AVC), marginal revenue (MR), and average total cost (ATC) curves for a firm that sells mid-range cars in a competitive market. Use the area tool to draw the area representing the firm's profit or loss, if the firm produces 6,000 cars. Your answer should be a rectangle drawn with four corners.
The table below shows the weekly marginal cost (MC) and average total cost (ATC) for Buddies, a purely competitive firm that produces novelty ear buds. Assume the market for novelty ear buds is a competitive market and that the price of ear buds is $6.00 per pair. Buddies Production Costs MC ($) Quantity of Ear Buds 5 10 15 20 25 30 35 40 2.00 2.45 3.55 4.00 5.50 5.98 8.52 pairs ATC ($) 2.00 2.00 2.15 2.50 2.80 3.25 3.64 4.25 Check my work Instructions: In part a, enter your answer as the closest given whole number. In parts b-d, round your answers to two decimal places. a. If Buddies wants to maximize profits, how many pairs of ear buds should it produce each week? b. At the profit-maximizing quantity, what is the total cost of producing ear buds? c. If the market price for ear buds is $6 per pair, and Buddies produces the profit-maximizing quantity of ear buds, what will Buddies profit or loss be per week? d. Now assume the market price is $5.50 per pair, and Buddies produces the…
Giocattolo is a profit-maximizing firm producing toy cars, which it can produce and sell in its home country, Italy, and abroad in Spain. The average cost (AC) curve on the following graph represents Giocattolo's cost of producing toy cars within one factory, whether in Italy or in Spain. COST (Dollars per toy car) 10 1 0 10 I 1 20 30 40 50 60 70 80 QUANTITY (Thousands of toy cars) AC 90 100 Suppose that at the current market price of toy cars, the demand for Giocattolo's product is 10,000 toy cars per year in Italy and 20,000 toy cars per year in Spain. (Hint: Select each point on the previous graph to see its coordinates.) (?) Based on Giocattolo's average cost curve, within one factory it can produce 20,000 toy cars at S per toy car, and produce the total of 30,000 toy cars at S per toy car. Complete the following table by indicating Giocattolo's total production cost for each scenario. Total Production Cost (Dollars) Scenario Produce 10,000 toy cars in Italy and 20,000 toy cars in…

Suppose that each firm in a competitive industry has the following costs: where q is an individual firm’s quantity produced. The market demand curve for this product is where P is the price and Q is the total quantity of the good. Currently, there are 9 firms in the market. What is each firm’s fixed cost? What is its variable cost? Give the equation for average total cost. Graph average-total-cost curve and the marginal-cost curve for q from 5 to 15. At what quantity is average-total-cost curve at its minimum? What is marginal cost and average total cost at that quantity? Give the equation for each firm’s supply curve. Give the equation for the market supply curve for the short run in which the number of firms is fixed. What is the equilibrium price and quantity for this market in the short run? In this equilibrium, how much does each firm produce? Calculate each firm’s profit or loss. Is there incentive for firms to enter or exit? In the long run with…
Consider the competitive market for sports jackets. The following graph shows the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves for a typical firm in the industry. For each price in the following table, use the graph to determine the number of jackets this firm would produce in order to maximize its profit. Assume that when the price is exactly equal to the average variable cost, the firm is indifferent between producing zero jackets and the profit-maximizing quantity. Also, indicate whether the firm will produce, shut down, or be indifferent between the two in the short run. Lastly, determine whether it will make a profit, suffer a loss, or break even at each price.
