Marissa has 4.5 feet of ribbon that she wants to use to tie some boxes. If 1 foot of ribbon is left after Marissa uses 0.7 feet of ribbon to tie each box, find out how many boxes she tied?
Thoughts? Step-by-step reasoning:
Marissa used a total of 4.5 - 1 = 3.5 feet of ribbon to the boxes. Thus, there were 3.5 / 0.7 = 5 boxes.
Thus, the answer is 5.
