Francine has five full boxes of crayons and 5 loose crayons, and her friend has 27 loose crayons. They need to put all of their loose crayons in a box. How many more boxes do they need if Francine has a total of 85 crayons?
Thoughts? Step-by-step reasoning:
Francine has 85 - 5 = 80 crayons in total that are in the boxes. Thus, each box of crayons is filled with 80 / 5 = 16 crayons. A total of 5 + 27 = 32 crayons need to be placed in the boxes. Therefore, they still need 32 / 16 = 2 boxes for the loose crayons.
Thus, the answer is 2.
