Suppose Kate's Great Crete (KGC) is a monopolist and has annual variable costs of VC = 30Q + 0.0025Q2 and marginal costs of MC = 30 + 0.005Q,where Q is the number of cubic yards of concrete it produces per year. In addition, it has an avoidable fixed cost of $50,000 per year. KGC's marginal revenue function is MR = 50 - (1/200) Q and demand function is Qd = 20,000 - 400P. What is KGC's profit at the profit maximizing sales price?
