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?

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}.

Let's assume the cost of one month of game play is "x" dollars.

According to the given information, Angie buys 1 software package and 1 month of game play, which costs $45 + x dollars.

Kenny buys 2 software packages and 2 months of game play, which costs (2 * $45) + (2 * x) dollars.

The total cost for Angie and Kenny is $168.

So we can set up the equation:

(1 * $45 + x) + (2 * $45 + 2x) = $168.

Now, we can simplify the equation:

$45 + x + $90 + 2x = $168.

Combining like terms:

$135 + 3x = $168.

Subtracting $135 from both sides:

3x = $168 - $135.

3x = $33.

Dividing both sides by 3:

x = $33 / 3.

x = $11.

Therefore, the cost of one month of game play is $11.

To solve this problem, we will use algebraic equations. Let's denote the cost of one month of gameplay as "x".

According to the problem:

Angie buys 1 software package and 1 month of gameplay.
Kenny buys 2 software packages and 2 months of gameplay.

The cost of each software package is $45. So, Angie spends $45 on software and x dollars on one month of gameplay.

Similarly, Kenny spends $45 x 2 = $90 on software and x dollars x 2 = 2x dollars on two months of gameplay.

Thus, the total cost of Angie and Kenny's purchases is $45 + x + $90 + 2x = $168.

Combining like terms, we have 3x + $135 = $168.

Subtracting $135 from both sides of the equation, we get 3x = $168 - $135.

Simplifying, we have 3x = $33.

Finally, dividing both sides of the equation by 3, we find that x = $11.

Therefore, the cost of one month of gameplay is $11.
