Suppose a firm's total cost curve is TC = 5Q² + 6Q + 125. The firm's marginal cost is MC = ____. A) 10Q + 6 B) 5Q + 6 + (125/Q) C) 5Q + 6 D) 5Q² + 6Q

Question

Quizplus · Accepted Answer

The marginal cost (MC) is found by taking the first derivative of the total cost (TC) function with respect to quantity (Q). The derivative of TC = 5Q^2 + 6Q + 125 with respect to Q is MC = 10Q + 6.
