Total paid ($48) equals price per hour ($5) times the number of hours (x) plus $18 per hour.
x= number of hours
Equation:
$5x + $18= $48
Solve:
$5x + $18= $48
Subtract $18 from both sides
5x= 30
Divide both sides by 5
x= 6
Check:
Substitute x=6 in equation
$48= $5x + $18
48= 5(6)+18
48= 30+18
48=48
Hope this helps! :)
