Skyler's age is 72 and Kori's age is 24.

Step-by-step explanation:

Step 1: From the given details, form equations. Let the age of Skyler be x and that of Kori be 96 - x (since their sum is 96).
Step 2: Considering their ages 8 years ago, form equations.

⇒ (x - 8) = 4 (96 - x - 8)

⇒ (x - 8) = 4 (88 - x)

⇒ (x - 8) = 352 - 4x

⇒ 5x = 360

⇒ x = 72

Step 3: Calculate Kori's age

⇒ 96 - x = 24

2. Tickets to a play cost $344.50 for a group of 12 adults and 10 children. Each aduit ticket cost

Drupady [299]

Each kid ticket will cost 12.25 dollars because 18.50 times 12 equals 222 dollars. You subtract 222 from 344.50 to get the total amount for 10 kids which is 122.50 dollars. 122.50 divides by 10 is 12.50.
