Question

Jillian works 2 jobs. She earns $8.25 her first. She earns $10.15 at her second. If Jillian earned a total of $387 by working `x` hours at her first job and `y`hours at her second job, how do you write an equation that represents this situation?

Answer 1

`$8.25x +$10.15y = $387`

Explanation:

Jilian's first job pays `($8.25)/(1 "hour")` while her second job pays `($10.15)/(1 "hour")`.

Since we know she works `x` number of hours for first job and `y` number of hours for second job, we can set the equation up like this:

Total earned = `($8.25)/(1cancel( "hour"))xx x cancel( "hour")+($10.15)/(1 cancel( "hour")) xx y cancel( "hour")=$387`

Simplify, and we get:
`$8.25x +$10.15y = $387`
