    You can find out what the "average" amount would be. Which would be (3+4+0.5)/3.

    Great. Yes. So how much would Kate have to give to Lily so Kate would be left with 2.5 c

    Yeah, I couldn't easily develop a formula to determine all of this at once so I just figured out how much everyone should have to be equal and then figured out how much Kate and Max had to give up.
