Question

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

Marissa has $28.50 this month to spend on movie rentals.
How many movies can she view this month?

Answer 1

Marissa can rent 18 movies this month

Explanation:

Step 1, make an equation.

5+1.25x=28.50

Step 2, solve the equation until the x is alone.

x=18.8

The real answer is 18 because she is short on 20 cents to be able to rent 19 movies.

Answer 2

18 movies

Explanation:

1) Subtract the monthly charge from Marissa's total allowance

28.50 - 5.00 = 23.5

2) Divide 23.5 by the charge per movie.

23.5/1.25 = 18.8

3) Since there cannot be 4/5 of a movie, Marissa can spend enough to watch 18 movies.
