If the question you are asking is how much is a ticket, if 7 tickets cost a total of 56 dollars, then the answer is 8. This is because you would divide the total cost bu how many there are, which would look like 56 / 7 = 8.
I did 17 X 25 to find out how much she earned JUST from the warranty, which is 425. Subtract that from $1530 and get $1105. Divide that by 17 and get 65.
