Well, there are two different deals. Since these tickets are reusable, it's ok to have leftovers but we need the cheapest deal.
Good Idea! I'll solve for the 2nd deal, and you can solve for the first one
$5 for 25 tickets!
My ratio is 25 tickets to 5 dollars. 25:5 is another way of writing this. Now I need to multiply 25 times 1 and I need to multiply 5 times x. I end up with 25=5x. When I solve the equation I get x=5. So now I know that I get 5 dollars per ticket., that's my unit rate.
Hmm... so I need to know the Unit Rate of how much money per ticket, this will help me to figure out the better deal.
My first step is to set up my proportion. I need to put 36 over 12 and that will be equal to x over 1. If I do the butterfly method I learned in school. I will end up with the equation 36= 12x. When you do the math, you will see that x= 3. so you are paying for 3 tickets every dollar.
My goal is to find the unit rate of 36 tickets and 12 dollars for a ticket. This shouldn't be too hard.
