For the cost function C(Q)= 75 + 4Q + 2Q²,the marginal cost of producing 5 units of output is: A) 4. B) 54. C) 20. D) 24.

Question

Quizplus · Accepted Answer

The marginal cost function is the derivative of the total cost function with respect to Q. C(Q)= 75 + 4Q + 2Q² MC(Q) = dC/dQ = 4+ 2² So, to find the marginal cost of producing 5 units of output, we substitute Q = 5 in the marginal cost function: MC(5) = 4 + 2² MC(5) = 4 + 2(1)(2)(0) MC(5) = 4 Therefore, the marginal cost of producing 5 units of output is 4. So, the best choice is D.
