The Grapefruit Computer Company currently produces its desired level of output. Its marginal product of labor is 10, its marginal product of capital is 50, the wage rate is $20, and the rental rate of capital is $100. In this case, the firm should:.
a. employ more capital and more labor.
b. employ less labor and less capital.
c. employ less labor and more capital.
d. employ less capital and more labor.
e. not change its allocation of capital and labor.

d. employ less capital and more labor.

And also, high capital rate of $100, which is considerably higher than the labor wage rate of $20, the firm should employ less capital and focus more on labor
