Question

Billy has a gift card with a value of $150 . He buys several video games that cost $35 each and one $10 pair of headphones. After the purchases his gift card balance is $35. Write an equation to find the cost of each video game. Use g for video games

Answer 1

3 video games

Explanation:

The correct question is

Write an equation to find the number of video games Billy bought

Let

g ----> the number of video games Billy bought

we know that

The number of video games multiplied by its cost plus the cost of one pair of headphones must be equal to the difference between $150 and $35

so

The linear equation that represent this situation is given by

`35g+10=150-35`

solve for g

`35g+10=115\\35g=115-10\\35g=105\\g=3\ video\ games`
