The Car Rental Decision

Mathematics may be actually useful in making some decisions. Deciding on which company to use when renting a car or getting a phone service in a classic example. Let's use what we know about the calculator to solve this problem:

Can you help me with a car rental decision? I am doing a professional development for a district in Utah next week. Even though I'll only be there one day, it's quite a ride from the airport to the school where I am presenting. I want to use one of the three car rental companies I have had good experiences with before. The offers, shown below, do not include gas and taxes since they are the same for each plan.

Which plan will cost me the least?
