Q: A school library has 120 books. Each student needs 5 books for their classes. The library was able to help 4 students on the first day of school, 5 students on the second day and 6 students on the third day. How many students can the library help out on the fourth day of school?
A: On the first day, the library used 4 students * 5 books = 20 books. On the second day, the library used 5 students * 5 books = 25 books. On the third day, the library used 6 students * 5 books = 30 books. On the fourth day, the library had 120 books - 20 - 25 - 30 = 45 books remaining. The library can help 45 books / 5 books = 9 students on the fourth day. The answer is 9.

[Question]Gabriel is 3 years younger than Frank. The current total of their ages right now is 17. What is Frank's age?
[Answer]Let X be Frank's age. So Gabriel is X - 3 years old. The total of their ages is X + (X - 3) = 17 years old. 2X - 3 = 17. 2X = 20. X = 10. So Frank is X = 10 years old. The answer is 10.
Q: Six kids and two adults are going to the circus. Kid's tickets are on sale for only half of the adult tickets. The total cost is $50. How much is one kid's ticket?
A: Let X be the price of one kid's ticket. So the price of one adult ticket is X * 2. Five kids and two adults are going to the circus, so 6 * X + 2 * (X * 2) = $50. So 10X = $50. So the price of one kid's ticket is X = $5. The answer is 5.
