Algebra practice question
Three adult tickets and two child tickets to a fair cost $33. One adult ticket and two child tickets cost $19. What is the price, in dollars, of one adult ticket?
Answer: 7
Subtracting the second purchase from the first removes the child tickets: 2 adult tickets cost $14, so one costs $7.
Common wrong answers
- If you answered 6
- 6 dollars is the child ticket price; the question asks for the adult price.
- If you answered 12
- Subtract the full purchases first: (33 − 19) = 14 covers exactly 2 adult tickets.
- If you answered 14
- 14 dollars is the cost of two adult tickets; one costs 7.
