Answer:
Opportunity cost = $30,000
Step-by-step explanation:
Opportunity cost is the value of the next best alternative sacrificed in favor of a decision. Opportunity cost is also known as implicit cost. It is the value of the sacrificed made to take a course of action.
For example, should the person in question decides to go to college, that would mean him forfeiting the sum of $30,000 which he would have earned had he decide otherwise.
The accounting cost of going to college is amount is $15,000,the cost to be incurred.
While the economic cost would be the sum of the accounting cost plus the opportunity cost
Economic cost = 30,000 + 15,000 = $45,000
