The discussion revolves around calculating the cost per ticket when purchasing a roll of 25 tickets for 15 dollars, comparing this to the cost of single tickets priced at 75 cents each. Participants explore whether this is a proportion problem and how to derive the cost per ticket from the total cost and number of tickets.
Participants generally agree on the calculation yielding 0.60 dollars per ticket; however, there is some contention regarding the relevance of the single ticket price and the method of calculation.
Some participants express uncertainty about the appropriateness of using proportions in this context and the implications of different methods for calculating cost per ticket.
If you divide 25 tickets by 0.75 dollars you will have "tickets per dollar" when you want "dollars per ticket". But, anyway, the "75 cents each" is if you by single tickets and has nothing to do with buying a roll of tickets. You are told that you can get 25 tickets for 15 dollars. You want to determine "dollars per ticket" in this case. That is (15 dollars)/(25 tickets). 15/25= 3/5= 0.60.RTCNTC said:Tickets at a fair cost 75 cents each. You can also buy a roll of 25 tickets for 15 dollars. What is the total cost of each ticket if you buy a roll of tickets?
Is this a proportion problem?
Do I divide 25 by 0.75 to find the total price for each ticket?
