Question

Quizplus · Accepted Answer

The marginal product of the fourth worker is calculated by subtracting the total output produced by the first three workers from the total output produced by all four workers. The total output from the first three workers is 50 + 34 + 22 = 106 units. Given that four workers produce 116 units, the marginal product of the fourth worker is 116 - 106 = 10 units.
