Question

A movie rental website charges $5.00 per month for membership and $1.25 per movie.

Marisa has $18.50 this month to spend on movie rentals. How many movies can she view this month?
She thinks she can afford 11 movies in 1 month. What mistake could she be making?

Answer 1

Marisa can rent 10 movies this month including the $5.00 membership fee. Not including the membership fee she could rent 14 movies this month. Her mistake is was rounding the 10.8 up when she should have rounded it down, unless she can get 10 8/10 of a movie.
