Question

at smith's bike rentals, it costs $39 to rent a bike for 7 hours. how many hours of bike use does a customer get per dollar

Answer 1

39 dollars for 7 hours

We want unit rate of PER DOLLAR.

whatever quantity we want per that quanity, we divide.

So,

we will divide the number of hours by number of dollars.

hence,

`(7)/(39)`

hours.

7/39 hours worth of bike riding the customer gets PER DOLLAR.
