Refer to Table 13-3. If the total output with one worker is 10 units and with two workers is 18 units, what is the marginal product of the second worker?

• A. 8 units
• B. 10 units
• C. 18 units
• D. 28 units

Answer: (A)

Verified step by step guidance

1. Identify the total output when one worker is employed, which is given as 10 units.
2. Identify the total output when two workers are employed, which is given as 18 units.
3. Recall that the marginal product of a worker is the additional output produced by adding one more worker, calculated as the change in total output when the number of workers increases by one.
4. Set up the formula for the marginal product of the second worker: \(\text{Marginal Product}_2 = \text{Total Output with 2 workers} - \text{Total Output with 1 worker}\).
5. Substitute the values into the formula: \(\text{Marginal Product}_2 = 18 - 10\) to find the additional output contributed by the second worker.
