Jeff works two part-time jobs to make ends meet while attending college. He makes$6 an hour at the coffee shop and $8.45 an hour cleaning offices at night. If he worked 24 hours last week and made $180.75, how many hours did he work at each job?
Answer provided by our tutors
let he worked x hours in coffee shop
time worked in cleaning offices is (24-x)
So
6x + (24-x)8.45 = 180.75
x=9
So he worked 9 hrs in coffee shop and 15 hrs in cleaning offices
