Angie and Kenny play online video games. Angie buy 2 software packages and 4 months of game play. Kenny buys 1 software package and 1 month of game play. Each software package costs $25. If their total cost is $155, what is the cost of one month of game play.

Let s be the cost of software packages and m be the months of game play. We have:

• Angie: 2s + 4m
• Kenny: s + m

We are given each software package costs $25. So the revised equations above become:

• Angie: 2(25) + 4m = 50 + 4m
• Kenny: 25 + m

Finally, we are told their combined cost is 155. So we add Angie and Kenny's costs together:
4m + 50 + 25 + m = 155

Combine like terms:
5m + 75 = 155

Typing this into our search engine, we get m = 16
