Spacely Sprockets' short-run cost curve is: C(q, K) = + 15K, where q is the number of Sprockets produced and K is the number of robot hours Spacely hires. Currently, Spacely hires 10 robot hours per period. The short-run marginal cost curve is: MC(q, K) = 50 . If Spacely receives $250 for every sprocket he produces, what is his profit maximizing output level? Calculate Spacely's profits.
