Opportunity cost = $60, 000 /2
Opportunity cost = $30 000

Opportunity cost = 10% × $50,000
Opportunity cost =$5,000
Total opportunity cost = $60,000+$5,000
Total opportunity cost =$65,000
Third step is to find the total net profit
Total net profit=$40,000- $18,000
Total net profit =$22,000
Now let find the economic profit using this formula
