Question

One month ann rented 3 movies and 2 video games for a total of $25 . the next month she rented 5 movies and 6 video games for a total of $57 . find the rental cost for each movie and each video game.

Answer 1

3m + 2g = 25.....multiply by -3
5m + 6g = 57
-------------------
-9m - 6g = - 75 (result of multiplying by -3)
5m + 6g = 57
-------------------add
-4m = - 18
m = -18/-4
m = 4.50 <=== cost of each movie

3m + 2g = 25
3(4.5) + 2g = 25
13.5 + 2g = 25
2g = 25 - 13.5
2g = 11.50
g = 11.50/2
g = 5.75 <=== cost of each video game
