.
let F=fee; R=hourly rate=1.2F ; N=number of hours
Total charge=F+NR
Total charge=F+N(1.2F)
$470=F+7(1.2F)
$470=F+8.4F
$470=9.4F
$50=F ANSWER 1: Her fee is $50.
.
R=1.2F=1.2($50)=$60 ANSWER 2: Her hourly fee is $60/hour.
.
CHECK:
Total charge=F+NR
$470=$50+(7hours)($60/hour)
$470=$50+$420
$470=$470
