Answer:
correct answer is Sell the ticket because the marginal benefit exceeds the marginal cost
Explanation:
given data
plane = 200-seat
cost of flying = $100,000
empty seats = 10
marginal cost = $200
standby passenger willing to pay = $300
solution
as here we know Marginal benefit is $300 while marginal cost is $200
so as when airline continue to fill up remaining empty seats till marginal benefit is as that big as marginal cost
when marginal benefit is less than marginal cost so then airline stop selling
