Angie and Kenny play online video games. Angie buys 1 software package and 1 month of game play. Kenny buys 2 software packages and 2 months of game play. Each software package costs ​$45. If their total cost is ​$168​, what is the cost of one month of game​ play?

Answer 1

Let x be the cost of one month of game play.
Angie spends 45 + x dollars.
Kenny spends 2(45) + 2x = 90 + 2x dollars
The total spent is 45 + x + 90 + 2x = 3x + 135 dollars.
And 3x + 135 = 168 dollars.
So, the cost of one month of game play is (168 - 135)/3 = <<(168-135)/3=11>>11 dollars. Answer: \boxed{11}.
