Suppose the production function for a coffee shop is:
Q = 2K + 5L
Where Q is the number of cups of coffee produced, K is the number of coffee makers, and L is the number of workers. The function for the marginal product of capital is ____.
A) 5
B) 2.5
C) 2
D) 0.4

Question

Quizplus · Accepted Answer

The marginal product of capital (MPK) is the additional output produced by using one more unit of capital, holding other factors constant. In the given production function Q = 2K + 5L, the coefficient of K (capital) is 2, which represents the MPK. This means that for each additional coffee maker, the output (cups of coffee) increases by 2 units.
