A group of school volunteers bought a batch of nursing home milk and "sunset red" on the Double Ninth Festival to express their condolences to the elderly. If you give five boxes to each old man, there are still 38 boxes left. If each old man is divided into six boxes, then the last old man gets less than five boxes, but at least one box.

1. There are X old people in the nursing home, so how many boxes of milk are there? (represented by an algebraic expression containing x)

2. How many old people are there in this nursing home? How many old people are there at most?
