Angie and Kenny play online video games. Angie buys 1 software package and 1 month of game play. Kenny buys 1 software package and 4 months of game play. Each software package costs $20. If their total cost is $105 , what is the cost of one month of game play?

Step-by-step explanation:

As each software package costs $20

Angie and Kenny bought 2 software packages (1 each)

Hence firstly we will subtract their cost from total

=105 (20 + 20)

=105 - 40

= $65

This is the cost of 5 months of gameplay

hence, you just need to divide this value with 5 to get cost of 1 month of game play

= 65/5

= $13

The cost of one game play is equal to $13
