When you sign up for a movie service, you get three free months of movies. Then you are charged $15 per month to rent movies. If you pay $90, how many months of use do you get?

Given : 

First 3 months are free .

Charge per month after 3 months = $15

Total amount paid = $90

So, Number of paid months = Total amount/cost of 1 month

= $90/$15

= 6

So, total months of service = 3 + 6

= 9

 

Hence, movie service is used for 9 months in $90
