Explanation:
Note: The full question is attached
Price Q TR MR Output TC MC
2.75 3 8.25 - 3 4 -
2.50 4 10 1.75 4 4.5 0.5
2.25 5 11.25 1.25 5 4.75 0.25
2 6 12 0.75 6 5.75 1
1.75 7 12.25 0.25 7 7.75 2
For profit Max MR = MC. MC>MR
At Q = 5, MR = 1.25 & MC = 0.25
Economic profit = TR - TC = 11.25 - 4.75 = $6.5
But at Q = 6, MR = 0.75 MC = 1. Net benefit is negative
