For a fundraiser, Nellie needs to sell 45 rolls of gift wrap. So far, she has sold 1 roll to her grandmother, 10 rolls to her uncle, and 6 rolls to a neighbor. How many more rolls of gift wrap does Nellie need to sell?
Thoughts? Step-by-step reasoning:
The number of rolls already sold is 1 + 10 + 6 = 17. Nellie needs to sell 45 − 17 = 28 more rolls of gift wrap.
Thus, the answer is 28.
