For a school fundraiser, Chandler needs to sell 12 rolls of wrapping paper. So far, he has sold 3 rolls to his grandmother, 4 rolls to his uncle, and 3 rolls to a neighbor. How many more rolls of wrapping paper does Chandler need to sell?
Chandler has sold 3 rolls + 4 rolls + 3 rolls = <<3+4+3=10>>10 rolls.
Chandler still needs to sell 12 rolls – 10 rolls = <<12-10=2>>2 rolls.
