Mr. Smith had 32 markers in his classroom. He buys new boxes of markers that have 9 markers in each box. Now, he has 86 markers. How many new boxes did Mr. Smith buy? Give me reasons, before answering the question
Mr. Smith bought 86 markers - 32 markers = 54 markers. Mr. Smith bought 54 markers ÷ 9 markers / box = 6 new boxes. So the final answer is 6.
