Question

A rental car costs a onetime fee of $150 and then an additional $80 for each day it is rented. If the Nawa family's total bill was $470, for how many days did they rent the car?

Answer 1

Cost=150+ 80d....d=number of days
470=150+80d
470-150=80d
320=80d divide by 80
4=d
she rented the car for 4 days
