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?
