Question

The cable company charges a monthly fee of $45. Each movie rental is $1.99. You owe 68.88. How many movies did you rent?

Answer 1

Amount owed for movies =total amount owed - amounts charged by cable company
Amount owed for movies =68.88-45=23.88

Number of movies rented=amount owed for movies divided by amount per movie
Number of movies rented =28.88 divided by 1.99=12
Therefore you rented 12 movies

Answer 2

45+1.99x=68.88
Subtract 45 from both sides
1.99x = 23.88
Divide both sides by 1.99
X=12
