One movie club charges a $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: ________
Solve for the number of movies: ________
Answer (2)
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
To find when the costs of two movie clubs are equal, we set up the equation 100 + 10 x = 15 x and solve for x . This gives us x = 20 , meaning you would need to watch 20 movies for the memberships to cost the same. Therefore, watching 20 movies equalizes the cost between the two clubs.
