At this quantity, the marginal cost of the final phone case they produce is $ than the price received for each phone case they sell. At this point, the marginal cost of producing one more phone case (the first phone case beyond the profit maximizing quantity) is $ , an amount than the price received for each phone case they sell.

Aplia Homework: Production and Cost in the Firm 4. Profit maximization using total cost and total revenue curves Suppose Ana runs a small business that manufactures teddy bears. Assume that the market for teddy bears is a price-taker market, and the market price is $10 per teddy bear. The following graph shows Ana'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 teddy bears that Ana produces, including zero teddy bears. 125 100 75 P 0 2 QUANTITY (Teddy bears) 6 Total Cost ☐ 8 *** Total Revenue A Profit (?)
