### The Extra Dollar

Here is an old math puzzle that you can find many versions of online.

Two friends have a meal at a restaurant, and the bill is $25. The friends pay$15 each, which the waiter gives to the cashier. The cashier gives back $5 to the waiter. The friends tell the waiter to keeps$3 as a tip, so he hands back $1 to each of the two diners. So, the friends paid$14 each for the meal, for a total of $28. The waiter kept$3, and that makes \$31.
