Savannah is wrapping presents for her friends and family for Christmas. She has bought 3 rolls of wrapping paper to wrap 12 gifts. If it takes 1 roll to wrap 3 gifts and 1 roll to wrap 5 other gifts, if there is no wrapping paper leftover after Savannah wraps the rest of the gifts, how many gifts did she wrap with the third roll of paper?
What is the solution?
