3 guys rent a hotel room (I like it already!) for $30. After
they leave, the manager of the hotel realizes that she has overcharged
them. The room costs only $25. "Oh no!" she exclaims, "I have
overcharged them!" She promptly gives the bell hop the 5 bucks and tells
him to give it back to the guys. "Man, 3 guys and 5 bucks! How can I
possibly divide this equally without the use of multivariable calculas or
a powerful scientific solar powered calculator!" Thinking quickly, he
pockets 2 dollars and gives each of the guys 1 dollar back.
The guys renting the hotel room think something's fishy. If they
each payed $9 for a total of $27, and the bell hop kept $2, where is the
extra dollar? ($9x3=$27, $27+2=$29 -- where be the extra dollar!)
