3 guys walk into a hotel. The price for the room they want to share is $30.00. Each one puts down $10.00. (3 X 10) The manager tells them that since its Friday they can have the room for $25.00. He can't divide the $5.00 change evenly so he gives each man $1.00 and "pockets" $2.00 (3X1 + 2 = $5.00)

If each man now paid $9.00 ($10 - $1.00 refund)that equals $27.00 (3 X 9). And the manager "pockets" $2.00 which now equals $29.00. Where did the other dollar go?

9 dollars paid by each of the guys make 9 * 3 = 27
each man got one dollar back so 1*3 = 3
now they make a total of 30 dollars. the two dollars the manager pockets are actually from the 27 dollars paid by the three guys. so u cant add the pocketed 2 dollars to the already paid 27 dollars.
