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?
Mr. Smith bought 86 markers - 32 markers = <<86-32=54>>54 markers.
Mr. Smith bought 54 markers ÷ 9 markers/box = <<54/9=6>>6 new boxes.
