Answer/Step-by-step explanation:
Earns per hour: $5.50
1 time fee : $2
Total = $35
( h - hours)
Equation :
5.50h + 2 = 35
First step is to suntract 2 from each side:
5.50h + 2 - 2 = 35 - 2
Simplify
5.50h = 33
Divide each side by 5.50 to seprate h from the numbers:
5.50h/5.50 = 33/ 5.50
H = 6
ANSWER: 6 hours
