Question 924939
One month Lisa rented 2 movies and 3 video games for a total of $25
The next month she rented 4 movies and 8 video games for a total of $61
 . Find the rental cost for each movie and each video game.
----------------
Equations:
2m + 3v = 25
4m + 8v = 61
-----
Modify for elimination::
8m + 12v = 100
8m + 16v = 122
-----
Subtract and solve for "v"::
4v = 22
v = $5.50 (cost of a video game)
---
Solve for "m":
2m + 3v = 25
2m + 3*5.5 = 25
2m + 16.5 = 25
2m = 8.50
m = $4.25 (cost of a movie)
