Jeri's lawn service charges an initial fee of $4.50 plus $3 an hour. If she is asked to
start before 7 a. m., Jeri charges 1.5 times the regular amount. If she made $29.25
on a job that began at 5 am, how many hours did Jeri work?
h = the number of
hours
that Jeri worked
1.5(3h + 4.50) = 29.25
1.50 3
+ 1.5(4.50) = 29.25
4.5h + 6.75 =
I
6.75
4.5h =
- 6.75
22.5
22.5
4.5h
4.5
