Quizplus · Accepted Answer

The marginal product of labor is the additional output that is produced when one more unit of labor is added, holding all other inputs constant. In this case, when the second worker is added, output increases from 20 units to 32 units, which is a difference of 12 units. Therefore, the marginal product of the second worker is 12.
