3 MEN GO INTO A MOTEL. THE MAN BEHIND THE DESK SAID THE ROOM IS  $30, SO EACH 
MAN PAID $10 AND WENT TO THE ROOM.

A WHILE LATER THE MAN BEHIND THE DESK REALIZED THE ROOM WAS ONLY  $25, SO HE 
SENT THE BELLBOY TO THE 3 GUYS' ROOM WITH $5.  ON THE  WAY, THE BELLBOY 
COULDN'T FIGURE OUT HOW TO SPLIT $5 EVENLY BETWEEN 3 MEN,  SO HE GAVE EACH MAN A $1 
AND KEPT THE OTHER $2 FOR HIMSELF.

THIS MEANT THAT THE 3 MEN EACH PAID $9 FOR THE ROOM, WHICH IS A  TOTAL OF 
$27, ADD THE $2 THAT THE BELLBOY KEPT = $29. What happened to the  dollar?
