Math Mystery:   Three band members 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 band members. But he decides to cheat them and pockets $2.00. He then gives each man a dollar. Now each member 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?
