Where is the other dollar?

I tried to search, but it kept saying there was a server error, so sorry if this is a repeat . . . Three men go into a hardware store to buy a $30 lawnmower. They each have only a $10 bill which they give to the cashier. However, the cashier informs the men that the lawnmower is on sale for $25 and asks how they would like her to split the change of $5 between them. None of the men want change, so they ask her to give each of them a dollar back and she can keep the other $2. So, each man has paid $9 for the lawnmower. $9 x 3 men equals $27. Add the $2 that the cashier kept and you have $29. Where is the other dollar?

| You probably wouldn't have found it even if the search function was working well. This riddle is usually stated with three men renting a motel room, rather than buying a lawnmower.

The first time I heard it, it was a hotel bill, with the bellboy pocketing 2 dollars.

So, in year 4 before evergreena3, was it a restaurant bill, a motel bill, or something else?

I have an old german book printed in spring 1941 that contains this riddle. The first edition is in 1921, but I could have been added later. There, it is already a restaurant bill. Three men pay 10 "Krone" each, but the meal costs only 25, so the waiter takes 2 as a tip and returns one Krone to each. If we ever manage to find that missing coin, is there any chance to return it to its owner?

If each paid $10 and got $1 back, in the end they paid $9 each.

The correct distribution of the original $30 dollars is: $25 for the bill, $2 for the waiter/clerk/bellhop/whatever, $3 dollars for the 3 men. After their refunds, the men paid in a total of $27. $2 out of that $27 went to the person, and the remaining $25 paid the bill. The riddle purposefully turns this around by adding the $2 to the $27, when in fact the $2 are from the $27.

I used algebra and got: Let x be price($25) Let y be price paid($30) 3(y / 3 - 1) + 2 = y - 1 3(1/3y - 1) + 2 = y - 1 y - 3 + 2 = y - 1 y - 1 = y - 1 What I'm thinking is that it should be: 3(y / 3 - 1) - 2 = x y - 3 - 2 = x As y = 30 and x = 25, y - 5 = x.

It makes perfect sense... If 3 men gave $10 = $30 And it's on sale for $25 so then there would be $5 left. Each man got $1 back... $5-$3=$2 which the cashier keeps. And there isn't another dollar... Keep the $2 cause it's part of the $27... right? Wow I'm soo confused. I need some sleep ok bye now.
