Question

Item 6Item 6 Suppose that the firm's only variable input is labor. When 50 workers are used, the average product of labor is 50 and the marginal product of labor is 75. The wage rate is $80 and the total cost of the fixed input is $500. What is the marginal cost

Answer 1

Answer:

$1.07

Explanation:

The marginal cost measures the change in total cost of adding on more worker divided by the change in product for this additional worker (marginal product of labor). When adding one more worker, costs will increase by $80 (wage rate), while product will increase by 75. Therefore, the marginal cost is:

$MC=\frac{80}{75}\\MC=\ 1.07$

The marginal cost is $1.07.
