What kind of formula do i use to find out the cheapest rate to use for the car rental?
Mr. Smith wants to rent a Suv to go from home to a conference in Seattle, he expects to do 350 miles in total during this journey
There are 3 rental companies:
Hertzy RentalFixed rate of $58 dollars with no mileage charge
Alabo RentalCharge $.35 cents per mile
Nifty RentalCharge a fixed rate of $28 plus $.15 cents per mile

charge for x miles:
Hertz: 58
Alabo: .35x
Nifty: 28 + .15x
so, for 350 miles, you get
Hertz: 58.00
Alabo: .35(350) = 122.50
Nifty: 28 + .15(350) = 80.50
I guess it's easy now to tell which is cheapest for a 350mile rental.
