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. Found 2 solutions by TimothyLamb, stanbon:Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = price movie
y = price game
---
2x + 3y = 25
4x + 8y = 61
---
put the system of linear equations into standard form
---
2x + 3y = 25
4x + 8y = 61
---
copy and paste the above standard form linear equations in to this solver:

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)
