Topic A Problem: While on vacation, you go to a miniature golf course on a weekday and notice no other customers there while you golf. Why do you think a miniature golf course would stay open during the week when it seems like the revenue from so few customers could not possibly cover the costs of running the golf course? What is an example of another business that stays open even when it's slow, and their revenue does not seem like it could cover their costs? (Use as many economic terms as possible to explain.)
