Question: I'm stuck on this math problem: 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?
Can you help?
Answer: 
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.
