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 REALISED THE ROOM WAS ON SPECIAL AT ONLY $25, SO HE SENT THE BELLBOY TO RETURN THE  $5.

ON THE WAY, THE BELL BOY 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.

WHERE IS THE OTHER DOLLAR GONE TO ?
