One movie club charges a $100 membership fee and $10 for each movie. Another club charges no membership fee but movies cost $15 each. Write and solve an equation to find the number of movies you need to buy for the cost of each movie club to be the same.
The first movie club is y=10x+100 The second movie club is y=15x You can set them equal to each other getting 15x=10x+100 Subtract the 10x from both sides 5x=100 X=20 or the number of movies needed to make the amount be the same is 20 movies
