A market has inverse demand equation P=1350 Q. is All firms have the same cost function. The equation of the cost function C (g) = 72+6g+² (a) Find and graph the average cost equation and the marginal cost equa- tion. What amount of output minimizes a firm's average cost? What is the minimum value of average cost for a firm? If this market is perfectly competitive, what is the long-run equilibrium price and the long-run equilibrium number of firms? What is the amount of consumers' surplus in long-run competitive equi- librium? (b) Find the short-run equilibrium price, output per firm, and profit per firm if 75 firms supply the market.
