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? Let's think first. Chain of thought:
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.
Therefore, the answer is 13.
