Consider the price-taker 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 market. 100 90 80 70 60 ATC (Dollar) COSTS 8 8 30 20 10+ 0 O 30, 15 AVC 30 50 60 70 QUANTITY (Thousands of jackets) O MC- 90 100

Calculate Kenji's marginal revenue and marginal cost for the first seven shirts he produces, and plot them on the following graph. Use the blue points (circle symbol) to plot marginal revenue and the orange points (square symbol) to plot marginal cost. ? 30 8 COSTS AND REVENUE (Dollars per shirt) 25 15 O 10 0 0 1 2 5 QUANTITY (Shirts) 3 4 6 Kenji's profit is maximized when he produces 7 8 would maximize his profit) is $ which is maximizing quantity corresponds to the intersection of the last condition can also be written as Marginal Revenue shirts. When he does this, the marginal cost of the last shirt he produces is $ which is than the price Kenji receives for each shirt he sells. The marginal cost of producing an additional shirt (that is, one more shirt than than the price Kenji receives for each shirt he sells. Therefore, Kenji's profit- curves. Because Kenji is a price taker, this Marginal Cost

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. 100 90 70 60 ATC 40 30 20 AVC 10 + ++++ 10 15 20 3 30 35 o 5 QUANTITY (Thousands of jackets) 50 For each price in the following table, use the graph to determine the number ofr 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. Price Quantity (Dollars per jacket) (Jackets) Produce or Shut Down? Profit or Loss? 10 20 32 COSTS (Dollars)

Suppose Eileen runs a small business that manufactures shirts. Assume that the market for shirts is a competitive market, and the market price is $20 per shirt. The following graph shows Eileen's total cost curve. Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for shirts quantities zero through seven (inclusive) that Eileen produces. 200 175 Total Revenue 150 125 Total Cost Profit 100 50 25 -25 1 3 4 6 7 QUANTITY (Shirts) Calculate Eileen's marginal revenue and marginal cost for the first seven shirts she produces, and plot them on the following graph.

The following graph shows the daily cost curves of a firm operating in this market. V ATC AVC PRICE (Dolars per watch) 100 5 MO 0 0 10 20 30 40 50 60 70 80 90 100 QUANTITY(Thousands of watches) For each price in the following table, calculate the firm's optimal quantity of units to produce, and determine the profit or loss if it produces at that quantity, using the data from the previous graph to identify its total variable cost. Assume that if the firm is indifferent between producing and shutting down, it will produce.

Notes for graph: MC is marginal cost, MR is marginal revenue, ATC is average total cost, AVC is average variable cost and D is the demand curve. To maximize the profit, how many units should the firm produce? At what price? Based on your answer, what is the total revenue? Total costs? Total profit? Total fixed cost? Will you operate this firm in the short run? Long run? Briefly explain.
