Answer:
1.5 cars
Explanation:
Three employees can produce a total of:
= 4 × 3
= 12 cars in an hour.
Five employees can produce a total of:
= 3 × 5
= 15 cars in an hour
So, the increase in total product of labor as I increase the labor from 3 to 5 employees:
= Total product when 5 employees are hired - Total products when 3 employees are hired
= 15 - 12
= 3 cars.
So, the marginal product of moving from 3 to 5 workers:
= 3 ÷ 2
= 1.5 cars
