- Profit maximization using total cost and total revenue curves Suppose Caroline 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 Caroline'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 Caroline produces. Caroline's profit is maximized when she produces______ shirts. When she does this, the marginal cost of the last shirt she produces is ______, which is (GREATER OR LESS) than the price Caroline receives for each shirt she sells. The marginal cost of producing an additional shirt (that is, one more shirt than would maximize her profit) is _____, which is (GREATER OR LESS) than the price Caroline receives for each shirt she sells. Therefore, Caroline's profit-maximizing quantity corresponds to the…arrow_forwardam. 116.arrow_forwardThe supply curves for the only two firms in a competitive industry are given by: S₁: P = 2Q1 S2: P = 2 + Q2, where Q1 is the output of firm 1 and Q2 is the output of firm 2.

Suppose that this market is in long-run competitive equilibrium with many hot dog stands in the city, each one selling the same kind of hot dogs. Therefore, each vendor is a price taker and possesses no market power. The following graph shows the demand (D) and supply (S = MC) curves in the market for hot dogs. Place the black point (plus symbol) on the graph to indicate the market price and quantity that will result from competition. (?)

This firm buys up all the rest of the hot dog vendors in the city and operates as a monopoly. Assume that this change doesn't affect demand and that the new monopoly's marginal cost…arrow_forwardIn competitive markets, there are many small firms with each firm unable to influence the market price. Suppose company ABX operates in the wheat market. The company produces and markets wheats at a Price = $20 per container.

- Please slove the attached qustionarrow_forwardSuppose a typical (representative) corn farm has a short run production technology which results in the outcome of U-shaped Average Variable Cost (AVC), Average Total Cost (ATC), and Marginal Cost (MC). Further, suppose this firm sells its product in a market where the price of the good is determined by the interaction of market Demand and Supply. Because an individual firm is very small compared to the rest of the market, we treat the market price as the price given to the firm, and the individual firm cannot impact that price. assume we are in the Short Run for this firm. In graphing, put $ on the vertical axis and lower-case q (firm output) on the horizontal axis. Start with the AFC0, AVC0, ATC0, and MC0 curves . show shifts in any of the cost curves, reflecting the higher cost of land (keeping in mind that this higher cost is independent of how much or how little corn is actually produced) and labeling the changed cost curves with a subscript 1.
