Suppose market demand in a competitive market is Q = 1000 - 4p. If all firms have LRAC = 50 - 5q + q², how much is the market price in long-run equilibrium, and how many identical firms will there be when this industry is in long-run equilibrium? (Hint: the market price is equal to the minimum of LRAC, and the industry output is the sum of the productions of all individual firms).
