Q1. Numeral stores propose film developing as a examine to their customers. Suppose that each store offering this service has a cost function C(q) = 50 + 0.5q + 0.08q2 and a marginal cost MC = 0.5 + 0.16q. If the going rate for developing a roll of film is $8.50, is the industry in long-run equilibrium? Discover the price connected with long-run equilibrium?
