Final answer:
To make a decision about college using economic concepts, consider opportunity cost, incentives, and cost-benefit analysis.
Step-by-step explanation:
In making a decision whether to stay in Illinois for college or go somewhere warm, you can think like an economist by considering several economic concepts. One important concept to consider is opportunity cost. By staying in Illinois, you will pay less for tuition, but you will miss out on the experience of living in a new city and experiencing warm weather. This is the opportunity cost of choosing Illinois. Another concept to consider is incentives. Your parents prefer that you stay in-state and are willing to help you pay for college. This provides you with an incentive to choose Illinois. Cost-benefit analysis is another useful concept to consider. You should weigh the cost of out-of-state tuition against the benefits of experiencing new things and a new city.
