Question

Amanda rented a bike from Ted's Bikes. It costs $9 for the helmet plus $3.75 per hour. If Amanda paid about $40.88, how many hours did she rent the bike? a) Let h = the number of hours she rented the bike. Write the equation you would use to solve this problem.

Answer 1

≈8.5 hrs

Explanation:

find the equation h would equal to 3.75

`3.75h+9= 40.88`

Next subtract 9 out from both side of the equation

`3.75h+9 -9= 40.88-9`

`3.75h= 31.88`

Divide 3.75 out of both sides of the equation

`(3.75h= 31.88)/(3.75)`

`h=8.50133`

Round to the nearest tenth

≈
`8.5`
