Three traveling salesmen stop for the night at a budget hotel and ask for rooms. The clerk apologises and tells them that he has only one room. "Its on special tonight." he adds, "just $30.00" The three men look at each other and say "what the heck." "$10.00 each."

Later on, the clerk realises that he over cherged the three men. The special was for $25.00 a night. Calling the bell hop over, he hands him a five dollar note and tells him to take it back to the three men.

Now, the bell hop is a smart young lad. Three people cannot equally divide five dollars so he fishes in his jeans and takes out three, one dollar bills.

Knocking on the door of the three men, he hands each one of the a dollar. "Overcharge, sorry."

Now 10 - 1 = 9.00 per salesman. 9 x 3 = 27.00 in total, plus the 2.00 the bell hop kept = $29.00

What happened to the missing dollar?

I get thinking harder and harder on science every time I don't understand something. AND do, elements are made out of atoms, which consist of protons, neutrons, and electrons... BUT, what makes up them? What makes an electon's mass so much smaller than a proton's mass? WHAT IS the string theory

THANKS to those who are answering to all my electron questions (see I got started on this topic because I was studying photosynthesis, and how electrons need "special carriers" to be transported, so that got me thinking about electrons) anyway, why, in basic terms, do high-energy electrons seem to be further away from the nucleus?
