Suppose Honda’s total cost of producing 4 cars is $225,000 and its totalcost of producing 5 cars is $250,000. What is the average total cost of producing 5 cars?
What is the marginal cost of the fifth car? • Draw the marginal-cost curve and the average-total-cost curve for a typical firm, and explain why these curves cross where they do.
