Question

uan went out to lunch with five friends. They decided to divide the bill evenly among them. Juan estimated that his lunch cost $5.25. The entire bill came to $37.20. Would Juan’s lunch have cost more or less if he paid for it separately? How much more or less?

Answer 1

Well the answer is that the answer is irrelevant. This is a social situation rather than a merely mathematical one. Because it was agreed upon among Juan and his five friends to split the bill, that's ... kind of the sum of it.
