2nd attempt then...

Basically your neighbour has given you $100 and you've given her $100 so that evens out.
The customer has basically taken the headphone (that you brought for $80) and $10 as well.

So either your down $90 (the $80 for the headphone plus their $10 "change")
Or maybe $100 (the $90 you were selling it for plus their $10 "change")
Or maybe (as a headphone dealer) you totally write off the costs of the headphone in amongst normal day to day running costs so your only $10 out of pocket.

Or (alternatively) your not down anything as you've got the $100 "fake" and you can claim the actual cash back from somewhere or other ???

80 + 10 + 100 + 100 = $290 in the hole

-$170

You lost 80 up front and 100 on the back end.

However you made 10 by getting legit change.

Doesn't it depend on whether or not you knew that you had a fake $100?

If you know that you've got a fake $100, then you start out $100 in the green, technically. If you didn't know it, then you got screwed somewhere earlier, and you're $100 in the red to begin with.

$110

The $100 the customer gave you was fake.

1. Pay $80 for Player: Total -80
2. Receive $100: +20
3. Give $100 to Neighbor: -80
4. Receive 100 From Neighbor: +20
5. Give $10 to Customer: +10
6. Give $100 to Neighbor: -90

The two statements in bold above don't make sense. The neighbor gave you $100, not the reverse. You gave the neighbor $10 change. Sounds like a scam to me

Looking at where actual money changes hands. You give out 80 for the phones. You get $90 of headphone stock. You get 100 from your neighbour. You give 10 to the customer/conman. You lose 90 in stock. You lose 100 in cash to your neighbour

-80
+90
+100
-10
-90
-100

All adds up to you being $90 in the red.

Did you think this up yourself?

Hmm. So then what's the trick?

Assuming no taxes, or that you don't have operating profits or can't otherwise utilize the net operating losses, I agree with the others that you're out 90 (as a net loss). Otherwise, a simple tax impact would be you're out 90 * (1-t), with t being the tax rate. This all assumes that you need to write off the $100 as a fraud expense.

But if this is the trick you're looking for, this isn't a simple math question. It's a simple accounting/tax question.
