Answer: She had an economic loss of $8,000.
Explanation:
Economic profit = Accounting profit - Opportunity cost
Accounting profit = Revenue - Total Cost.
Monica's Opportunity cost is the amount she would have been earning if she didn't start her business. It is $50,000.
Total cost = $1500 × 12 = $18,000
Accounting profit = $60,000 - $18,000 = $42,000
Economic loss = $42,000 - $50,000 = $ -8000
