Ron isn’t sure how a pair of sunglasses can cost more than a color television. On a recent trip to the Sunglass Hut to pick up a pair of new sunglasses, he encounters a salesperson who tries to convince him that the elimination of UV rays makes the glasses worth their price tag. Ron, not so politely, disagrees.
Molly (Madeline Carroll) and her dad Bud (Kevin Costner) are driving down the road, but Bud is unhappy with egg salad sandwich as a lunch option. Molly quickly points out that they are on a budget and that if he wants to eat better then he needs to drink less beer. This tradeoff can be illustrated with a budget constraint in economics. Given a fixed level of income, the only way to get more (or better) food, is to give up something else.
