Answer 2

Hello :) why don't we try to make equations from the information given to us?

(office hours) + (cashier hours) = 55 hours
and (amount per hr)*(office hour) + (amount per hr)*(cashier hr) = 585

if you would like to use variables
o + c = 55
12o + 8.25c = 585

do you know how to use system of equations to solve from there? :)
