one movie club charges a $100 membership fee and $10 for each movie. Another club charges no membership fee but the movie is $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.
Let x represent the number of movies you need to buy for the cost of each movie club to be the same.
For the first movie club, the cost would be $100 for the membership fee plus $10 for each movie, so the total cost would be 100 + 10x.
For the second movie club, there is no membership fee, and each movie costs $15, so the total cost would be 15x.
Therefore, the equation would be:
100 + 10x = 15x
To solve the equation:
First, subtract 10x from both sides:
100 = 5x
Then, divide both sides by 5:
20 = x
So, you would need to buy 20 movies for the cost of each movie club to be the same.
can u put it in formula form
Certainly! Here is the equation in formula form:
Total cost for Movie Club 1: $100 + $10x
Total cost for Movie Club 2: $15x
Setting these two expressions equal to each other gives us the equation:
$100 + $10x = $15x
Let's denote the number of movies as "x".
For the first movie club, the cost to join is $100, and each movie costs $10. Therefore, the total cost of the first club is given by the equation:
Total Cost = 100 + 10x.
For the second movie club, there is no membership fee, but each movie costs $15. Therefore, the total cost of the second club is:
Total Cost = 15x.
To find the number of movies needed for the costs to be the same, we can set the two equations equal to each other and solve for x:
100 + 10x = 15x.
Now we can solve for x:
100 = 5x,
x = 100 / 5,
x = 20.
So, you would need to buy 20 movies for the cost of each movie club to be the same.
