Question

Jon has to pay $8.00 admission for the skating rink and $1.25 per hour to rent rollerblades. How many hours can he skate for $20?

Answer 1

20-8=$12
then 12 divided by 1.25 equals 9.6.
9.6 hours is what he can stake

Answer 2

9.6 hours.

Explanation:

Let x be number of hours.

We have been given that John pays $1.25 per hour to rent roller blades. The cost of renting roller blades for x hours would be
`1.25x`.

Since he admission fee is $8, so total cost of skating for x hours would be
`1.25x+8`.

To find the number of hours that John can skate in $20, we will equate
`1.25x+8` by 20 as:

`1.25x+8=20`

`1.25x+8-8=20-8`

`1.25x=12`

`(1.25x)/(1.25)=(12)/(1.25)`

`x=9.6`

Therefore, John can skate for 9.6 hours.
