The table above shows a perfectly competitive firm's widget production and cost schedule. Suppose that the prevailing market price is $6.
(a) Fill in the blanks of the table above.
(b) Find the profit-maximizing quantity using the condition MR = MC.
(c) Calculate the maximum profit using the following formula: Profit =(P − ATC)×Q
(a) Fill in the blanks of the table above.
Q | TC | ATC | MC |
0 | 9 | ||
1 | 10 | 10 | 1 |
2 | 12 | 6 | 2 |

5 | 24 | 4.8 | 5 |
6 | 30 | 5 | 6 |
7 | 49 | 7 | 19 |
ATC=TC/Q
MC= change in TC/change in Q
(b) Find the profit-maximizing quantity using the condition MR = MC.
6 units.
Explanation:
firm maximizes its profit where MR=MC. in perfect competition price=MR. so, at Quantity 6, MR equals MC.
(c) Calculate the maximum profit using the following formula: Profit =(P − ATC)×Q
firm maximizes its profit where MR=MC. here profit maximizing quantity is 6.
Profit =(P − ATC)×Q
=(6-5)*6
=6.
