Each firm in a perfectly competitive market has long run average cost represented as AC(q) = 100q- 10+100/q. Long run marginal cost is MC=200q-10. The market demand is Qd = 2150-5P. Find the long run equilibrium output per firm, q*, the long run equilibrium price, P*, and the number of firms in the industry, n*. P = 190; Q = 1200; q =1 , n = 1200

There is an equilibrium price of $60 in a perfectly competitive market for a good that can be produced in continuous quantities. One firm in this market has a marginal cost of $60 at q = 15. If this firm produces q =15, it has an economic profit of -$400. Which of the following statements are true? i) if the firm has fixed costs of $300, then q =15 is the profit maximizing quantity in the short run for this...
