Answer:
3 workers
Step-by-step explanation:
Number of Total Production Marg. Product Marg. Revenue
employees of Labor Product
0 0 0 0
1 18 18 $180
2 30 12 $120
3 41 11 $110
4 46 5 $50
in order to maximize profits, the company must produce until the marginal revenue product ≥ cost of hiring an additional worker. In this case, the company should hire 3 workers since the MRP ($110) ≥ $100.
