Our new math problem of the week is:

The Disappearing Dollar

Three friends have a meal in a restaurant and they are charged $25.  They each chip in with a $10 bill and hand it to the waiter.  The waiter, though, isn't very good at math (like dividing the $5 change by 3), so he keeps $2 as a tip and hands each friend $1. 

Everyone seems pretty happy with the deal until one of the friends starts thinking about it.  The three of them paid $10 each but got $1 back, so that means that they spent $9 each.  And since there were three of them the total was 3 x $27, plus the $2 tip for the waiter.  That takes the total to $29.
