4. In a perfectly competitive market, market demand is given by Qd = 10000 - 100P and market supply is given by Qs = 150P - 300. Each firm has MC = .2Q + 2 and ATC = . 1Q + 2. Suppose the market is not in equilibrium and market price is P = $30. How many firms would be producing in the market? a. 20 C. 40 b. 30 d. 50 5.
