Answer:
a). Accounting profit=$80,000
b). Economic profit=-$10,000
c). It would be better to stop running the store since the opportunity cost of doing other things is higher. This means, it would be less costly if you decide to be an accountant and rent your store.
Explanation:
a). Accounting profit
The accounting profit can be expressed as;
P=R-E
where;
P=accounting profit
R=total revenue
E=expenditure
In our case;
R=$200,000
E=cost of bikes+electricity, taxes and other expenses
E=(100,000+20,000)=$120,000
replacing;
P=(200,000-120,000)=$80,000
Accounting profit=$80,000
b). Economic profit
The economic profit is the accounting profit including other opportunity costs. This means that if you decided to become an accountant and rent your store you would get total opportunities;
total opportunity cost=accountant yearly salary+rent
Total opportunity cost=(40,000+50,000)=$90,000
Economic profit=accounting profit-total opportunity cost
Economic profit=80,000-90,000=-$10,000, since the economic profit is negative, it would be advisable to exit the market
c). It would be better to stop running the store since the opportunity cost of doing other things is higher. This means, it would be less costly if you decide to be an accountant and rent your store.
