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

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
