d.)$3,250
e.) $250
Explanation:
a) John's accounting profit is his revenue minus his explicit costs:$5,000 - $4,250 = $750
b) In this case, John's opportunity cost of running the café is $725 per year ($1,000 − $275 = $725). Thus, the café is making an economic profit of $25 per year ($5,000 − $4,250 − $725 = $25). Since the café is earning an economic profit, John should stay in the café business.
c) In this case, John's opportunity cost of running the cafe is $825 per year ($1,100 − $275 = $825). Thus, the cafe is earning an economic loss of $75 per year ($5,000 − $4,250 − $825 = −$75). Since the café is earning an economic loss, John should not stay in the café business.
d) John's accounting profit equals his revenue minus his explicit costs. If he doesn't need a loan, then his explicit costs equal $3,250. So, his accounting profit equals $1,750 (= $5,000 − $3,250).
e) To earn a normal profit, the café would have to cover all its implicit and explicit costs. The opportunity cost of John's time is $1,000 per year while the café's accounting profit is only $750 per year. Thus, the café would have to earn additional revenues of $250 per year in order for John to make a normal profit.
