Its annual demand function is Qd = 10000 100P where P is the price in dollars of a cubic yard of concrete and Q is the number of cubic yards of concrete per year. What is KCCs marginal revenue when it sells 4000 cubic yards? (b) What is KCCs marginal revenue curve? (c) What is KCCs price when it sells 4000 cubic yards? (d) Suppose its marginal costs are $40 per cubic yard and it has avoidable fixed costs of $40000 per year. What are its profit-maximizing sales quantity and price?
