Answer:
Economic profit =$645,000
Step-by-step explanation:
Economic profit is the difference between revenue and out of pocket expenses plus opportunity cost.
Opportunity cost is the value of the benefit sacrificed in favour of a decision. It is the value of the next best alternative forgone in favour of a decision.
For example, the opportunity cost of the farmer is the interest rate he would have earned had he invested the money in savings account plus the salary forgone as a salesman
Economic profit = Revenue - out-of-pocket expenses - opportunity cost
Opportunity cost = interest foregone + salary forgone
= (1% × $1,000,000) + 45,000 = 55,000
Out of pocked trading expenses = 110,000 + 90,000 = $200,000
Revenue = $3 × 300,000 = $900,000
Economic profit = 900,000 -200,000-55,000= $645,000
Economic profit =$645,000
