3 friends go to a restuarant to eat. Their bill comes to $25. They each have $10 bills so they give $30 to the waitress/waitor. The waitress/waitor puts $25 in the cash register, keeps $2 tip for herself and gives them each back 3 $1 bills. Each person takes $1. So now each person has paid $9. 9x3=27, the waitress has $2, this adds up to $29, so what happened to the $1 bill?

The 30 dollars covered:

$25(put into the cash register.)+$3(given back as change.)+$2(dollar tip.)=$30

There is no lost/extra dollar bill.

i think the question seems difficult if you believe the question is being asked correctly. taking a step back helps see why the question is flawed.

the problem with the question is makes no sense add $27 and $2 to "recover" all thirty dollars. the $27 is ALREADY ACCOUNTING the amount paid as tip (in addition to the tab).

the $27 dollars reflects "tab+tip." if you add the $2 tip to this, you're essentially doing this: "tab+tip+tip."

so raindodger is right, the way to account for the $30 is to say $25 is in the register, $2 is in the waitperson's pocket, and $1 in each of the 3 customers.

As someone who waited tables for 4 years while taking all the prereqs for med school, if you are in the habit of leaving 8% tips, your real question should go something like this: If 3 friends go out to a restaurant and leave $2 on a $25 tab, why are the tires of their car slashed in the parking lot?
