You are a member of your local movie theater’s club. Every time you see a movie at the theater, you earn 4 advantage points. When you earn 100 points, you get a free movie pass.
Currently, you have 40 advantage points.
Write an equation to model the number of movies m, you have to watch before you earn a free movie pass.
Solve the equation. Show your work.
Let m represent the number of movies watched before earning a free movie pass.
We know that for every movie watched, 4 advantage points are earned.
To earn a free movie pass, the total advantage points earned must be 100.
So, the equation to model this situation is:
40 + 4m = 100
Subtracting 40 from both sides:
4m = 60
Dividing by 4 on both sides:
m = 15
Therefore, you would need to watch 15 more movies to earn a free movie pass.
