You are a member of your local movie theater's club. Every time you see a movie at the theater, you earn 2 advantage points. When you earn 100 points, you get a free movie pass. Currently, you have 40 advantage points.

Question

1. Write an equation to modle the number of movies m you have to watch before you earn a free movie pass.
2. Solve the equation. Show your work.
I need help writing the equation. I have this so far;
2m=100
m=50 (100÷2=50)
40÷2=20
50-20=30

Answer 1

40 + 2m = 100

Your equation shows how many movies will get you 100 points.
You did some more work and arrived at the correct answer, but you were asked to write an equation whose solution would provide the answer.
