                    as a whole must make choices. One way for a society to make choices is simply to allow
                    them to emerge out of many individual choices. For example, there are only 168 hours   Economists have special

                    ests and preferences. Economists call the value of the next best alternative that you
                    must give up when you make a particular choice an opportunity cost.         The real cost of an item is its
                       Opportunity costs are crucial to choices because, in the end, all costs are opportu-  opportunity cost: the value of
                    nity costs. That’s because with every choice, an alternative is forgone — money or time   the next best alternative that
                    spent on one thing can’t be spent on another. If you spend $10 on a pizza, you forgo   you must give up in order to get
                    the opportunity to spend that $10 on a hamburger. If you spend Saturday afternoon at   the item.
                    the park, you can’t spend Saturday afternoon doing homework. And if you attend one
                    school, you can’t attend another.
                       The park and school examples show that economists are concerned with more than
                    just costs paid in dollars and cents. The forgone opportunity to do homework has no
                    direct monetary cost, but it is an opportunity cost nonetheless. And if the local college
                    and the state university have the same tuition and fees, the cost of choosing one school
                    over the other has nothing to do with payments and everything to do with forgone
                    opportunities.
                       Now, suppose tuition and fees at the state university are $5,000 less than at the
                    local college. In that case, what you give up to attend the local college is the ability to
                    attend the state university plus the benefit you could have gained from spending $5,000
                    on other things. So the opportunity cost of a choice includes all the costs — whether or
                    not they are monetary costs — of making that choice.
                       The choice to go to college at all provides another important example of opportu-
                    nity costs. High school graduates can either go to college or seek immediate employ-
                    ment. Even with a full scholarship that would make college “free” in terms of monetary
                    costs, going to college would still be an expensive proposition because the time spent
                    on schoolwork can’t be spent earning money. By going to college, students forgo the
                    income they could have earned if they had gone straight to work instead. Therefore,
                    the opportunity cost of attending college is the value of all necessary monetary pay-
                    ments for tuition and fees plus the forgone income from the best available job that
                    could take the place of going to college.
                       The opportunity cost of going to college is high for people who could earn a lot
                    during what would otherwise be their college years. Soccer standout Mallory Pugh
                    withdrew from her first year in college because the opportunity cost of continuing
