Three buisness women need to rent a car for a day. the cost is $30 so they each pay$10. as they approach their rental car, the owner at the counter says "wait theres been a change. its your lucky day. the fee is only $25. heres $5 back." since the women are in a hurry and do not want to split the $5 they give the owner a $2 tip and they keep $3. so each women paid $10-$1 (money they each got back) = $9, times 3 is $27. If you add the $2 tip u get $29!!! wheres the extra dollar?

Think of it as a whole, with one person. ONE person gives him $30. ONE person receives $3 back. (subtract) That is a total of $27. You don't then add the extra $2... that is money that should have been returned, meaning it too would have been subtracted along with the other $3, making it then a total of $25.

There is nothing wrong. You have to take it as two separate problems.
First: The original price of the car was $30. That was easily divided between the 3 women.
Second: When they went to get the car, the found they had overpaid. They were given the $5 back. Each took a dollar, and left two for the top 2 + 3 = 5. Simple math.
Everything is fine, until you get an accountant (or the asker of this question) to look at the problem. They see things from a different angle. They look at it as the 3 women each paid $9 for the car. 9 * 3 = $27. Add in the $2 tip. 27+2=29. 29 does not equal 30, so where is the problem?
There really isn't any problem. No dollar is lost. You just have someone looking at it from a different way. Its called accounting tactics.

The three women each paid $9 for the car for $27, the $25 rental for the car plus the $2 tip.
The way the story is told, the $2 tip is counted twice, once by them paying it and once by the clerk receiving it. Similarly, the $3 returned is not counted at all. By not counting $3 and double counting the $2 there is a counting error of $1 which is the "other dollar" you are looking for.

Your math is wrong in the question -- they each paid $27. $2 of that $27 was the tip, and $25 was the cost of the car.
10-1 = 9
9x3 = 27
27 (total) - 25 (cost of the car) = 2 (the tip)

They paid $27. $25 for the car and $2 for the tip.

the two dollar tip is already figured in to the $27... 25 for the rental, plus 2 makes 27, then the three dollars they all got back... grand total... $30.00

each women paid 9 for a total of 27
25 of that 27 went into the cost for the room
2 of that 27 went as tip
there is no problem
