A perfectly competitive firm's average fixed cost function is AFC = 30/Q, its average variable cost function is AVC = 6 + 0.1Q, and it marginal cost function is MC = 6 + 0.2Q. The firm optimizes by producing the level of output that maximizes profit or minimizes loss. If the market price of the good is P = $12, then how many units of output will be produced? How much profit or loss will be earned or lost?
