Roxanna's normal hourly pay is $ 12
<u>Solution:</u>
Lets assume Roxanna's normal hourly pay = "x"
As overtime pay is 1.5 times of normal pay
So Roxanna's overtime hourly pay = 
Also given in 4 hours, in overtime Roxanna earned $72.00
So in 1 hour, in overtime Roxanna earned = 
That means Roxanna's overtime hourly pay = 18
Also we have calculated Roxanna's overtime hourly pay in terms of "x" that is 1.5x
=> 1.5x = 18
=> 
Roxanna’s normal hourly pay = x = $12
4+x=7
Move +4 to the other sign. Sign changes from +4 to -4.
4-4+x=7-4
x=3
Answer: x=3
