Mathematics: A group of 12, 8th graders are planning a graduation trip to Knotts Berry Farm. If you pre-buy a ticket online, you get a $34 discount for each ticket. If the group paid a total of $660, how much does a ticket cost without the discount?

Total ratio is 1 + 3 + 5 = 9Share for 1 = 1/9 × 144 = 16kgShare for 3= 3/9 × 144 = 48kgShare for 5= 5/9 × 144 = 80kgProof= 80 + 48 + 16 =144...

Each ticket costs $89.

Step-by-step explanation:

Let be x = ticket cost without the discount.

Given: Total 8th graders = 12

Discount = $34

Price of ticket after discount = x- 34

Total amount paid = $660

Total amount paid = (Price of ticket after discount) x (Total 8th graders )

$\Rightarrow\ 660=(x-34)(12)$

Divide both sides by 12.

$\Rightarrow\ 55=x-34$

Add 34 both sides , we get

$\Rightarrow\ x= 55+34\Rightarrow\ x=89$

Hence, Each ticket costs $89.
