Question

One month leila rented 3 movies and 8 video games for s total of $50. The next month she rented 5 movies and 2 video games for a total of $21. Find the rental cost for each movie and each video game,

Answer 1

Each move is $2 and each video game is $5.50.

To solve this we can write and solve the system of equations below.

3x + 8y = 50
5x + 2y = 21

If we multiply the bottom equation by -4, we can solve with elimination.

3x + 8y = 50
-20x + -8x = -84

-17x = -34
x = 2

If you sub in 2 for x, you can solve and find that y is 5.5.
