Impossible question!!!!!!!!
3 guys walk into a motel, and pay $30.00 to share a room. (Each guy pays $10) The clerk realizes the room should only be $25.00. The clerk takes 5 - $1 bills up to return to the men. They didn't want to split the $5 - 3 different ways to they each took $1, and gave the clerk $2 as a tip. Each guy payed $9 after they were returned their other dollar. $9X3guys = $27. The clerk only kept his $2. $2+$27 = $29.00. Where did the last dollar disappear to?

The dollar did not vanish. The men essentially received $1.67 each back out of the $5. Then the men tipped the clerk .67 cents each.
Multiply $1.67x3 and that gets your $5.00.
Multiply .67x3 then subtract this amount from the original $5 and that is the $3 that the men kept leaving $2 to give to the clerk.

HUH??? The 3 men got back $1.00 each as stated in the first thread.....not $1.67
It's a twister question as it makes it appear the men paid $27 for the room, but the room was only $25.

$1.67 * 3= %5.01 That really throws the math off.
.67*3=$2.01 .
You're really not helping matters.

I think
It has something to do with multiplying 9 by 3. If you go through the equation in the original order a dollar (YES Intellectualist) does truly end up vanishing.

Lee, you caught it.
No they did not. The only way you can find the $1 is if you take into account the men received $5 and split it between them and then each of the men forked over an equall amount to the clerk to come up to $2.
My method still works but it I guess now that I read it again it is a little more confusing my way!!!

If you try to figure this out without going through the necessary steps, you will never find the dollar!
Dollar isn't missing, the wording of the question is a twister to make it appear $1 is missing.
If you do elementary math that I posted above, you know there is not a missing dollar and don't need to do the crazy math you did above that didn't even add up right LOL.

They originally paid 30. Not 25. Received 5 in change. Gave 2 to bell boy, and split the 3 evenly. If you give a 10 for something and get 1 back in change you only paid 9.

They paid $30 originally.
They received a refund of $5 for the room since the clerk overcharged $5 for the room.
So that means that the room now cost $25.
The $5 refund they were given, each person kept $1 for $3.
$5 minus the $3 they kept leaves $2.
They give that remaining $2 to the clerk now leaving $0.00.
Thus $30 original room price - $5 refund = $25 new room price + $3 they kept + $2 tip = $30
I showed my math , now show your math to show the missing $1.
Here it is in subtraction:
$30 - $2.00 Tip = $28 - $3.00 they kept = $25 - $25 room price = $0.00

The original post
They each paid 10, got 1 in change equaling 9 a piece.
9*3 is 27.
Clerk got 2 ==== 29
