Question: Teresa is collecting pencils. She has 14 colored pencils and 35 black pencils. Her three younger siblings need pencils for class and their dad asks her to share all her pencils, giving each an equal number of pencils, regardless of color. He tells her she can keep 10 of them for herself. How many pencils does each sibling get?
Answer: Teresa has 49 pencils because 14 + 35 = 49. Teresa gives away 39 pencils because 49 - 10 = 39. Each sibling gets 13 pencils because 39 / 3 = 13. The answer is 13.

Q: Jamal works at a library shelving books. He has a cart full of books to put away in different sections. In the history section, he shelves 12 books. In the fiction section, he shelves 19 books. In the children’s section, he shelves 8 books but finds 4 that were left in the wrong place that he adds to his cart to shelve elsewhere. He still has 16 books to shelve. How many books did he start with in the cart?
A:
Jamal started with B books in the cart. He had B - 12 books after the history section. He had B - 12 - 19 = B - 31 books after the fiction section. He had B - 31 - 8 + 4 = B - 35 books after the children’s section. He still had B - 35 = 16 books to shelve. Thus, he started with B = 16 + 35 = 51 books in the cart. The answer is 51.
