Question

One movie club charges $100 membership fee and $10 per movie. Another club charges no membership fee but movies are $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?

Write the equation_____________

Answer 1

the first club charges 100 dolars staarting fee and 10 dollars per movie so
100+10x
x represents how many times they go

second club 15x

so we want to find out whenthey will be equall so

100+10x=15x
subtract 10x from both sides
100=5x
divide both sides by 5
20=x
so you need to go 20 times to get the same value
