A perfectly competitive firms 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.

B. produce 30 units of output and earn a total profit of $360
C. produce 60 units of output and suffer a total loss of $360
D. produce 60 units of output and suffer a total loss of $720
