Question 90093: Please help!
A car rental company has two rental rates. Rate 1 is $72 per day plus $0.18 per mile. Rate 2 is $144 per day plus $0.09 per mile. If a car is rented for one day, how many miles would you need to drive to pay less by taking Rate 2?

You can put this solution on YOUR website!
I recategorised your question so you can get help more quickly and so other people can reference it.
Rate 1 = 72 + 0.18m
Rate 2 = 144 + 0.09m
Set the equations equal and you will get m = 800.
Therefore, you will need to drive at least 800 miles so that Rate 2 is more economical for you.
