Question

If one movie club membership costs $100 fee and $10 cost per movie, and another club charges you no membership fee but each movie costs $15, what is an equation that finds the number of movies you need to buy for the cost of each movie club to be the same?

Answer 1

15x = 100 + 10x

Explanation:

"If one movie club membership costs $100 fee and $10 cost per movie"

This can be represented as:

100 + 10x

"charges you no membership fee but each movie costs $15"

This can be represented as:

15x

If you want an equation that can find it to cost the same:

15x = 100 + 10x
