One month Mai rented

6 movies and 2 video games for a total of

$36. The next month she rented 3

movies and 5 video games for a total of $39. Find the rental cost for each movie and each video game.

I believe that it's:

6 + 2 = 8; 36 : 8 = 4.5

3 + 5 = 8; 39 : 8 = 4.875

The first thing we must do for this case is to define variables:

x = rental cost of movies

y = rental cost of video games

We write the system of equations:

6x + 2y = 36

3x + 5y = 39

Resolving we have:

x = 4.25 $

y = 5.25 $

Answer:

The rental cost for each movie and each video game is:

movies = 4.25 $

video games = 5.25 $
