the missing dollar
Three men decided to split the cost of a hotel room. The hotel
manager gave them a price of $30.
The men split the bill evenly, each paying $10, and went to their
room. However, the hotel manager realized that it was a Wednesday
night, which meant the hotel had a special: rooms were only $25. He
had overcharged them $5!
He called the bellboy, gave him five one-dollar bills and told him
to return it to the men.
When the bellboy explained the situation to the men, they were so
pleased at the honesty of the establishment that they promptly
tipped the bellboy $2 of the $5 he had returned and each kept $1
for himself.
So each of the three men ended up paying $9 (their original $10,
minus $1 back) totalling $27, plus $2 for the bellboy makes
$29.
Where did the extra dollar go?
