Question

Terrance and Lakendra are going to GameStop for a new video game controller and some new games. Their grandmother gave them a $125 gift card for this purpose. If the controller they want is $45 and games are $20 each, what is the maximum number of games they can purchase (their father will be paying the sales tax)? Write your answer in the form g=8

Answer 1

Well, they are definitley buying a 45 dollar controller.
And in the end the total will be 125.
Let's set up the equation.
If we know they are buying a 45 dollar controller for sure,
we can put that in the equation first
45+ __=125
We need to know how many games they can buy.
Lets make the variable g for games.
each game is 20 dollars each.
So if we want to figure out how many games, it will be 20g.
Lets put that into the equation as well.
45+20g=125
Understood? any questions so far?
