Thread: Something to help make your head explode

I gave this problem to my students. So far none of them have been able to solve it. I can't blame them, it took me a long time to figure it out. So I thought I would share it with you all. After all, that is why we are here, to help share the madness.

If you figure it out you can pm me the answer, don't spoil it for others who are still working on it.

Here it is:

Three people have lunch together.
The bill is $25.
They each pay $10.
From $30 they get $5 change.
They give a $2 tip to the waiter.
That leaves $3.
They give $1 back to each person.
Each person has paid $9.
$9 multiplied by 3 = $27.
Plus the $2 tip = $29.
Where did the extra $1 go?

There is no extra dollar

But I won't spoil the figuring

Oh, there's an extra dollar all right!! That bastard waiter stole it!!!

See, this is why I think double entry book keeping should still be taught in schools.

I was thinking sales tax but wouldn't want to give it away. What I want to know is Who's on first ?

Edit; Thanks Lee, I just got it.

Sounds like Mr. Pink ..... if you don't get that go to youtube and watch."Reservior Dogs - Tips For The Tippers". I can't post that on SRP or I'd get banned.

If you can't post a link to that clip I will wait until I get home to look it up. Might not be a good idea to watch it at school.
