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

Jilian's first job pays $\frac{$ 8.25}{1 hour}$ $($8.25)/(1 "hour")$ while her second job pays $\frac{$ 10.15}{1 hour}$ $($10.15)/(1 "hour")$ .

Since we know she works $x$ $x$ number of hours for first job and $y$ $y$ 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 = $387$

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 xxx hours at her first job and yyyhours at her second job, how do you write an equation that represents this situation?
