Answer:
$-12,000
Step-by-step explanation:
Economic profit is accounting profit less implicit cost or opportunity cost.
Economic profit = Accounting profit - Opportunity cost
Accounting profit = total Revenue - total Cost
$260,000 - $230,000 = $30,000
Opportunity cost is the cost of the next best option forgone when one alternative is chosen over other alternatives.
The opportunity cost of Rosemarie starting her own restaurant is the salary she woold have been earning if she didn't leave her job = $12,000
Also the opportunity cost of using the space she inherited is the rent that would have been paid if she didn't use it as a restaurant = $30,000
Total opportunity costs = $30,000 + $12,000 = $42,000
Economic profit = $30,000 - $42,000 = $-12,000
