The lunch bill for three people is $25. Each person wanted the bill divided evenly, so they each contributed $10 and asked for $1 in change. The waiter kept $2 for a tip and gave the remaining change to the patrons. If each person paid $9 for the lunch and the waiter kept $2 for a tip, then what happened to the other dollar?
