Consumerism Math

Question

Company A rents cars for $27 per day and 9¢ per mile driven. Company B rents cars for $19 per day and 12¢ per mile driven. You want to rent a car for one day. Find the maximum number of miles you can drive a Company B car if it is to cost you less than a Company A car. (Give your answer as a whole number.)

Answer 1

Let x = number of miles driven

19 + 0.12x < 27 + 0.09x

0.03x < 8

x < 266.666

If you drive 266 miles or less, Company B is cheaper.
