2. Profit maximization of a seller in a competitive price-searchermarketConsider Unico Doughnut, a doughnut shop in a competitive price-searcher market. The following graph shows its demand curve, marginal revenue(MR) curve, marginal cost (MC) curve, and average total cost (ATC) curve. Assume that the shop is operating in the short run.Place the black point (plus symbol) on the graph to indicate the profit-maximizing price and quantity. If the shop is making a profit, use the greenrectangle (triangle symbols) to shade in the area representing its profit. If the shop is suffering a loss, use the purple rectangle (diamond symbols) toshade in the area representing its loss.PRICE (Dollars per doughnut)4.003.503.002.502.001.501.000MC005ATCDemand10 15 20 2.5 3.0 3.5 40QUANTITY (Thousands of doughnuts)MRAt the profit-maximizing output and price, the shop's profit is equal to 3Given the profit-maximizing choice of output and price, there areProft Maximizing OutcomeProfitLoss.(Hint: Be sure to enter a minus sign if profit is negative.)shops in the industry than there would be in long-run equilibrium.

3. Profit maximization using total cost and total revenue curves Suppose Sam runs a small business that manufactures shirts. Assume that the market for shirts is a perfectly competitive market, and the market price is $20 per shirt. The following graph shows Sam's total cost curve. Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for the first seven shirts that Sam produces, including zero shirts.

The graph shows a firm in a perfectly competitive market making a profit. The graph includes the firm's marginal cost curve, average total cost curve, and average variable cost curve. Assume the market price is $28. 1.) Use the line drawing tool to graph the firm's demand curve. Label this line 'Demand'. 2.) Use the point drawing tool to plot the firm's profit-maximizing price and quantity. Label this point 'Point A'. 3.) Use the rectangle drawing tool to shade in the firm's profit (Profit/Loss). Properly label this shaded area. Carefully follow the instructions above, and only draw the required objects. Price and cost 48- MC 44- 40- 36- 32- ATC 28- AVC 24- 20- 16- 12- 8- 4- Quantity
