Q: Peggy fell off her bike and skinned her knees. She needed two bandages on her left knee and three bandages on her right knee. If the box of bandages had 8 less than two dozen bandages before Peggy skinned her knees, how many bandages were left in the box after Peggy finished putting bandages on her knees?
A: 11
Explain how we arrive at this answer:
Explanation: Two dozen is 12 * 2 = 24. Eight less than two dozen bandages is 24 - 8 = 16 bandages. She needed two bandages on her left knee and three bandages on her right knee for a total of 2 + 3 = 5 bandages. Therefore, after Peggy finished putting bandages on her knees there were 16 - 5 = 11 bandages remaining in the box.
