Solution

a

Profit Maximization Condition: To maximize profits, the firm should produce where Marginal Revenue (MR) equals Marginal Cost (MC)

b

Given Data: The table provides the Marginal Cost (MC) and Marginal Revenue (MR) for different quantities of hours

c

Analysis: We need to find the quantity where $MR = MC$. From the table:
- At 1 hour: $MC = 40$, $MR = 100$
- At 2 hours: $MC = 30$, $MR = 100$
- At 3 hours: $MC = 20$, $MR = 100$
- At 4 hours: $MC = 30$, $MR = 100$
- At 5 hours: $MC = 40$, $MR = 100$
- At 6 hours: $MC = 50$, $MR = 100$
- At 7 hours: $MC = 60$, $MR = 100$
- At 8 hours: $MC = 70$, $MR = 100$
- At 9 hours: $MC = 80$, $MR = 100$
- At 10 hours: $MC = 90$, $MR = 100$
- At 11 hours: $MC = 100$, $MR = 100$
- At 12 hours: $MC = 110$, $MR = 100$
The quantity where $MR = MC$ is at 11 hours

Answer

(B) 11
