Suppose Felix runs a small business that manufactures frying pans. Assume that the market for frying pans is a perfectly competitive market, and the market price is $20 per frying pan. The following graph shows Felix's total cost curve.
Suppose Larry runs a small business that manufactures shirts. Assume that the market for shirts is a price-taker market, and the market price is $10
per shirt.
The following graph shows Larry'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 Larry
produces, including zero shirts.

Firms in the market are producing output but are currently incurring economic losses. How does the price of fertilizer compare to the average total cost, the average variable cost, and the marginal cost of producing fertilizer? Draw two graphs, side by side, illustrating the present situation for the typical firm and for the market. Assuming there is no change in either demand or the firms’ cost curves, explain what will happen in the long run to the price of fertilizer, marginal cost, average total cost, the quantity supplied by each firm, and the total quantity supplied to the market.arrow_forward
