Question

An instructor makes `$15` more per hour than an assistant. If the combined hourly wage of the instructor and assistant is `$65`, what is the hourly wage of the assistant?

Answer 1

The assistant´s hourly wage is `$25`.

Explanation:

If we consider the assistant´s hourly wage as `x`, then the instructor´s hourly wage will be `(x+15)`. Since we know the combined hourly wages, we can calculate the assistant´s wage as follows.

`x+(x+15)=65`

Open the brackets and simplify.

`x+x+15=65`

`2x+15=65`

Subtract `15` from both sides.

`2x=50`

Divide both sides by `2`.

`x=25`
