Quizplus · Accepted Answer

The marginal product of the fourth unit of labor is the difference in output between using 3 units of capital and 4 units of capital, with 4 units of labor. From the table, we can see that the output with 3 units of capital and 4 units of labor is 148, and the output with 4 units of capital and 4 units of labor is 164. Therefore, the marginal product of the fourth unit of labor is 164 - 148 = 16.
