Answer:
$33,000
Step-by-step explanation:
Economic profit = accounting profit - implicit cost
Accounting profit= total revenue - explicit cost
Explicit cost includes the amount expended in running the business. They include rent , salary and cost of raw materials
Implicit cost is the cost of the next best option forgone when one alternative is chosen over other alternatives
Accounting profit = $510,000 - $300,000 = $210,000
Implicit costs = amount he would forgo as salary in the large law firm and interest he would lose on his investment
Interest he would lose on his investment = 0.05 x 140,000 = $7000
Implicit cost = $170,000 + $7000 = $177,000
Economic profit = $210,000 - $177,000 = $33,000
