Question: Anya washes 32 hairs down the drain when she washes her hair and brushes out half that amount when she brushes it. How many hairs does Anya have to grow back to always have one more hair than she started with after washing, brushing, and growing it? Think carefully first, then make a decision:
Anya brushes out 32 / 2 = 16 hairs. To always have the same amount of hair, Anya has to grow back 16 + 32 + 1 = 49 hairs. So the answer is 49.
