- 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 $20 per shirt. The following graph shows Caroline's total cost curve. Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for shirts quantities zero through seven (inclusive) that Caroline produces. Caroline's profit is maximized when she produces______ shirts. When she does this, the marginal cost of the last shirt she produces is ______, which is (GREATER OR LESS) than the price Caroline receives for each shirt she sells. The marginal cost of producing an additional shirt (that is, one more shirt than would maximize her profit) is _____, which is (GREATER OR LESS) than the price Caroline receives for each shirt she sells. Therefore, Caroline's profit-maximizing quantity corresponds to the…Output Total Revenue ($) Total Variable Cost ($) Total Fixed Costs 1 1,000 750 500 2 2,000 1,250 500 3 3,000 2,000 500 4 4,000 3,000 500 5 5,000 4,500 500 What is the slope of the total revenue curve?

- 3. The components of marginal revenue Asim's HookNLadder is the only company selling fire engines in the fictional country of Alexandrina. Asim initially produced seven trucks, but then decided to increase production to eight trucks. The following graph gives the demand curve faced by Asim's HookNLadder. As the graph shows, in order to sell the additional fire truck, Asim must lower the price from $100,000 to $50,000 per truck. Notice that Asim gains revenue from the sale of the additional engine, but at the same time, he loses revenue from the initial seven engines because they are all sold at the lower price. Use the purple rectangle (diamond symbols) to shade the area representing the revenue lost from the initial seven engines by selling at $50,000 rather than $100,000. Then use the green rectangle (triangle symbols) to shade the area representing the revenue gained from selling an additional engine at $50,000.

Use the orange points (square symbol) to plot the short-run industry supply curve for the wheat industry. Specifically, place an orange point at the lowest point of the supply curve and another orange point at the highest point of the supply curve. (Hint: You can disregard the portion of the supply curve that corresponds to prices where there is no output, since this is the industry supply curve. Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.) 2. Place the black point (plus symbol) on the graph to indicate the short-run equilibrium price and quantity in this market.
