Missing Dollar-lmj20

To solve the missing dollar paradox, I worked backwards to discover that there was never a missing dollar. The way that the situation is worded makes it seem that each woman paid nine dollars, the waiter took two, and then there would be one missing dollar. However, the $27 that the women paid, $9 each, included the tip to the waiter. Adding the 27$ with the two dollars the waiter took would be counting the tip twice. Instead, the $27 includes the tip and the missing three dollars are the three dollars that the women received back from the waiter.
