at Redbox mike rents 2 DVD's and 3 games for total of $15.50. At the same time John rents 3 DVD's and 1 game for a total of $12.05. write a system of equations that represents this scenario. Clearly indicate what your variables represent in the context of this problem.
Accepted Solution
A:
D = DVDs
G = Games
Mike's formula 2D + 3G = 15.50
John's formula 3D + 1G = 12.05
If you multiple John by three and subtract from John you get the following.
-7D = -20.55
This is the same as 7D = 20.55
D = 2.94
Plugging that into John's, you get 3(2.94) + 1G = 12.05
8.82 + G = 12.05
G = 3.23
