Answer 1

Answer: Option (d) is correct.

Step-by-step explanation:

Correct option: For the 10th worker, the marginal revenue product is $120 per day.

If she hires 9 workers then the store can sell 200 pounds of produce per day

If she hires 10 workers then the store can sell 230 pounds of produce per day

Extra units produce from hiring 10th worker = 230 - 200 = 30 pounds of produce per day

Store earns = $4 for each pound

Therefore, the marginal revenue product for the 10th worker = selling price of each pound × Extra units produce from hiring 10th worker

= $4 × 30

=$120
