Otto's brother Dent Carr is in the auto repair business. Dent found that the total cost of repairing s cars is c(s) = 4s2 + 1600. Marginal cost MC(s) = 88. (a) This implies that Dent's average cost is equal to variable cost is equal to his average Plot average cost, average variable cost, and marginal cost curves. And also plot Dent's supply curve. (b) If the market price is $200, how many cars will Dent be willing to repair? If the market price is $320, how many cars will Dent repair? (c) Suppose the market price is $320 and Dent maximizes his profits. On the graph you draw in (a), shade in and label the following areas: total costs, total revenue, and total profits.
