Answer:
3 1/3 hours
Step-by-step explanation:
First we need to find how much she gets paid per hour. We can find this by diving the pay by the hours worked. Let x equal the pay per hour.
90/5=x
We can simplify the fraction by diving both the numerator and denominator by 5
(90/5)(5/5)=x
Do the division
18/1=x
Gianna gets paid 18 dollars per hour.
Now to find how much she needs to work we can divide the money she wants by the pay she gets per hour. Let y be the number of hours she needs to work.
60/18=y
turn into a mixed number
3 1/3=y
She would need to work 3 1/3 hours to make $60
