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

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 #
