Roxana's normal hourly pay is $12.
Step-by-step explanation:
Overtime pay = $72.00
Hours = 4
Pay of one overtime hour = [tex]\frac{Overtime\ pay}{No.\ of\ hours}\\[/tex]
Pay of one overtime hour = [tex]\frac{72.00}{4} = \$18[/tex]
Let,
x be the amount of normal hourly pay.
As overtime is 1.5 of normal hourly rate, therefore,
1.5x=18
Dividing both sides by 1.5
[tex]\frac{1.5x}{1.5}=\frac{18}{1.5}\\x=\$12[/tex]
Roxana's normal hourly pay is $12.
