Suppose the production function is given by Q = 3K + 4L.What is the marginal product of capital when 10 units of capital and 10 units of labor are employed?
A) 3
B) 4
C) 11
D) 45

Quizplus · Accepted Answer

To find the marginal product of capital, we need to take the partial derivative of the production function with respect to K, holding L constant:

MPK = ∂Q/∂K = 3

Therefore, the marginal product of capital is 3 when 10 units of capital and 10 units of labor are employed.

As for the best choice, it's not clear what decision needs to be made based on this information alone. More context is needed to determine the best choice.
