**Week 4 pow 9/9 - 9/13**

3 men go into a hotel. The man behind the desk says a room is $30 so each man pays $10 and goes to the room.

A while later the man behind the desk realized the room was only $25 so he sent the bellboy to the 3 guys' room with $5. On the way the bellboy couldn't figure out how to split $5 evenly between 3 men, so he gave each man a $1 and kept the other $2 for himself.

This meant that the 3 men each paid $9 for the room, which is a total of $27 add the $2 that the bellboy kept = $29. Where is the other dollar?

"The pessimist sees difficulty in every opportunity. The optimist sees the opportunity in every difficulty."

Can you just smell that? It's the smell of brains hard at work. We're at it again, today we're going to help the painter.

Scott the painter is going to paint the floors of 16 rooms. He is in room #1. He can go through any door (see diagram). He cannot return to any room once he has painted it — slow drying paint! In what order should he paint the rooms? Obviously, #16 must be last.
