So you bought a pair of shoes for 30 dollars, but it turns out to not actually fit that well and you lost the receipt so you try to sell it. No one buys at first so you bring the price down to 20 dollars. A guy comes by with a fifty dollar bill and no change, so you go exchange the fifty dollar bill with a neighbour for fifty dollars in change and give the guy the shoes plus thirty dollars. Your neighbour comes back telling you that the fifty dollar bill was counterfeit and she wants her money back, so you end up paying her 50 dollars.

 

How much money did you lose?

60 bucks?

That'd be right if you don't count what the shoes are worth.

Buy shoes: -$30
Mark down shoes to $20: Still -$30
Take (Counterfeit) $50 from buyer to neighbor for change: $20
Sell shoes for $20: -$10
Neighbor finds out bill is counterfeit: -$60
Realize you gave the shoes away for nothing: -$80

So, the loss is $80.

But you started with no shoes.  It's not a net-loss.

You pay $30 for the shoes.

 

The neighbor gives you a $50 counterfeit bill, which is $0.

 

You give them $30 in change: $60.

 

She asks for a full refund, $50.

 

You end up losing a total of $110.

 

Tough shit, bro.

This is really a matter of whether or not the neighbor was telling the truth about the $50.

No, cuz either way you end up paying the neighbour 50 bucks because you don't go find out if he lied or not.

The answer is $60... I think.

You buy the shoes: -$30
You get fifty bucks from your neighbour: $20
You sell the shoes and give $30 dollars to the guy: -$10
You pay your neighbour $50 for the loss: -$60
