George and his dad are planning to attend the state fair. An adult ticket is $19. The price of an adult ticket is one third the price of a student ticket plus $15

Answer 1

I'm guessing the problem is wanting you to find the price of the student ticket.

Let s be the price of the student ticket. From the description:

19 = s/3 +15

s/3 = 19-15 = 4

s = 3 × 4 = $12
