For annual fee of $30, you can join a movie club that will allow you to purchase tickets for $5.50 each at your local theatre. the regular price for a ticket is $8. how many tickets you will have to buy through the movie club for the cost to equal that of buying regularly priced tickets?

Question

anonymous · Answer

So on one hand for the movie club, you have 30 + 5.5x
For non movie club people the total cost is 8x
we set them equal to each other and we get 30+5.5x=8x 
so, 30=2.5x, x=12
