Answer: is realizing an economic profit of $40
Explanation:
The total cost involved in the production will be:
Fixed cost = $100
Variable cost = $3 × 20 = $60
Total cost = $160
The selling price will be:
= $10 × 20
= $200
The economic profit will then be;
= Selling price - Cost price
= $200 - $160
= $40
