Answer:
You need to see 30 more movies to earn 100 points.
Explanation:
You earn 2 advantages points every time you see a movie at the theater.
You need to earn 100 points to get a free movie pass.
Currently, you have 40 advantages points.
If you watch m movies you get = 2m points
You have 40 points so you need = 100 - 40 more points
So the equation will be = 2m = 100 - 40 [after combining like term]
2m = 60 [divide both side by 2]
m = 30
You need to see 30 more movies to earn 100 points.
