Three salesmen goes to Las Vegas. They arrive at the hotel and each of them has to pay $10 each for the night. Later the manager comes by and says they have a special going on this weekend. He told the receptionist to take $5 and devide it between the three salesmen, they paid too much. The receptionist then goes to give them the $5 and thought "It's too difficult to devide $5 between three, I'm gonna keep $2 and give them each $1 back". If he gives back each salesman $1, hom much did each pay for the night? What is the total of the three all together? Now plus the $2 the receptionist kept? What happened to the other dollar?

This is a classic old question. Nothing happened to the other dollar because there is no other dollar.
You think that each paid $10. Then they each get one dollar back.
So now each paid just $9, and you add in the $2 tip so that gives $29.00 -- leaving the mystery of the final dollar. However, each gentleman didn't just pay $9. If they had, the change would have been only $3.
They paid $25 in total, there's the $3 returned giving $28, and the $2 tip...for $30.

30 = 9*3 payed + ... 3 back in the pocket
9*3 = 27 = 25 for room + 2 as tip!
