Quizplus · Accepted Answer

The marginal productivity of the third worker is calculated by subtracting the total productivity (Q) with two workers from the total productivity with three workers. From the table, Q with two workers is 50 and with three workers is 90. Therefore, the marginal productivity of the third worker is 90 - 50 = 40.
