Ian paid $475 for an airline ticket to fly to Acapulco, Mexico for a spring break vacation. Unfortunately, he fell ill and could not go to Acapulco. When he called the airline to cancel the ticket, he was reminded that the ticket was non-refundable, but that he could exchange it for another ticket within one year if he pays a $75 fee at the time of the exchange. Several months later he is deciding whether to exchange the ticket for a ticket of the same price to Acapulco. The opportunity cost of go to Acapulco would equal the:
$75 exchange fee, if he has no other trip that he will take with in the year.

Joe has decided to purchase his textbooks for the semester. His options are to purchase the books via the Internet with next day delivery to his home at a cost of $250, or to drive to campus tomorrow to buy the books at the university bookstore at a cost of $245. Last week he drove to campus to buy a concert ticket because they offered 20 percent off the regular price of $20.
It would be rational for Joe to drive to campus because the $5 saving is more than he saved by driving there to buy the concert ticket.
In a two-person economy, Little Joe can trap a maximum of 6 rabbits or catch 10 fish a week, while his father can trap 12 rabbits or catch 15 fish per week. If their family wants to consume 20 fish per week while maximizing their joint production:
Little Joe should specialize in producing only fish, and his father should produce both fish and rabbits

With ATM machines it is possible to retrieve cash from the bank at any time. One hundred years ago, one could only get cash from the bank during business hours, say, 9 am to 3 pm. The difference is because
