Answer:
$ 17
Step-by-step explanation:
Let M represent month of game play
Each software package costs $45
Therefore, the cost of Angie and Kenny's software package
= $45 + $45
= $90
Angie buys 1 month of game play while Kenny buys 4 months of game play
Therefore they both buy 1 + 4 = 5 months of game play
Also, their total cost is $175
Now let's write an equation for their purchase
Price of software package + price of month of game play = 175
Slot in the respective values
90 + 5M = 175
Subtract 90 from both sides
90 - 90 + 5M = 175 - 90
5M = 85
Divide both sides by 5
M = 17
Therefore one month of game play = $ 17
