We have a system of linear equations:
Let S be the price of software package and M be the price of the month of game play.
Angie buys 1 software package and 3 months of gameplay, while Kenny buys 2 software packages and 2 months of game play. The total cost for them is $125.
We can write this as:
[tex]\begin{gathered} (1S+3M)+(2S+2M)=125 \\ 3S+5M=125 \end{gathered}[/tex]We also know that each software package cost $25. This can be written as:
[tex]S=25[/tex]We can replace this last equation in the first one, and calculate M:
[tex]\begin{gathered} 3S+5M=125 \\ 3(25)+5M=125 \\ 75+5M=125 \\ 5M=125-75 \\ 5M=50 \\ M=\frac{50}{5} \\ M=10 \end{gathered}[/tex]The cost of one month of game play is $10.
