Angie andKenny play online video games angie buys 1 software package and 3 months of game play. Kenny buys 1 software package and 4 months of game play. each software package costs $20. if there total cost is $117 what is the cost of one month game play

Angie buys 1 software package and 3 months of game play

Kenny buys 1 software package and 4 months of game play

price of each software package = $20

total cost = $117

cost of one month game play = ?

let y is the cost of one month play

Angie buys 3 months game play and paid $20 = 20 + 3y

Kenny buys 4 months game play and paid $20 = 20 + 4y

total cost of both is $117

So the equation becomes,

(20 + 3y) + (20 + 4y) = 117

7y + 40 = 117

7y = 117 - 40

7y = 77

dividing with 7 on both sides, we get

y = 11

so, $11 is the cost of one month game play
