Help me figuring it out...?

Question

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. WHERE IS THE OTHER DOLLAR?

Answer 1

This riddle is older than I am. There is no "other" dollar. The man at the desk has $25...the bellboy has $2,and the renters have &1 each. That totals $25

Answer 2

your brain is working over time
10+10+10=30
30-1-1-1=27
27+2=29
that leaves 1 for your overtime

Answer 3

I dont get it.
