Answer:
Accountant's profit = $70,000
Economist's profit =$16,000
Step-by-step explanation:
Economic profit is the difference between the sales revenue and the total of implicit cost and explicit cost
Implicit cost are opportunity costs The value of the sacrifice forgone in favour of a decision.
For example, in this question, salary of $50,000 and the interest of $4000 forgone.
Accountant definition
sales revenue less all costs with exclusion opportunity cost
Profit =250,000 - ( 20,000 + 120,000 + 40,000)
=$70,000
Profit from the economist definition
Interest on capital forfeited and salaries forfeited
= 250,000 - ( 20,000 + 120,000 + 40,000) - (50,000 + 4000)
= 260,000 - 180000 -54,000
=$16,000
