Three men go to stay at a motel and the clerk
charges them $30.00 for the room. They split the cost ten
dollars each. Later the manager tells the clerk that he over-
charged the men and that the actual cost should have been
$25.00. He gives the clerk $5.00 and tells him to give it to the
men. But he decides to cheat them and pockets $2.00. He then
gives each man a dollar. Now each man has paid $9.00 to stay in
the room and 3 X $9.00 = $27.00. The clerk pocketed $2.00.
$27.00 + $2.00 = $29.00.
So where is the other $1.00?
