A country faces a trade-off between producing cars and computers. If it chooses to produce more cars, which statement best reflects the opportunity cost involved?

When a country decides to produce more cars, the opportunity cost is what it gives up in order to make those cars. In this case, the country may have to reduce the number of computers it produces. This means that for every car made, fewer computers are available for sale or use. For example, if the country can make 100 cars or 200 computers, choosing to make 20 more cars might mean it can only produce 180 computers instead. So, the opportunity cost of making more cars is the computers that could have been produced instead.
