Problem
You want to buy a room air conditioner. The price of one machine is $200. It costs $20 a year to operate. The price of the other air conditioner is $300, but it costs only $10 a year to operate. Assuming that both machines last 10 years, which is a better deal? (Do you need to do extensive calculations to answer this question?)
