Answer:
Earning an economic profit of $600.
Step-by-step explanation:
Given that,
Firm is producing 300 units of output, P = $10
ATC of the 300th unit = $8
Marginal cost of the 300th unit = $10
AVC of the 300th unit = $6
Using the given information,
Economic profit = (P - ATC) × Q
Profit = (10 - 8) × 300
Profit = (2) × 300
Profit = $600
Earning an economic profit of $600.
