Fax has a garage sale. The cost of the sweater is $18. Fax sells it for $21. A person buys the sweater and gives Fax a $100 bill. Fax goes to his neighbor for change. He gives the buyer $79 back. The next day the neighbor tells Fax that the $100 is faked. Fax gives the neighbor back $100. How much money does Fax lose?

And $18 or $21, the value of the sweater that he's lost without getting a (legitimate) dime for it.

The confusion is that the OP says the "cost" of the sweater is $18 but someone pays $21 for it. The real number depends on what the real value of the sweater is to a legimate buyer paying in real cash. If the real value of teh sweater is $18, then the answer if $197. If $21, then $200. If something else, then $100+$79+[something else]

The first $100 is not FAX's, it's his neighbor's. FAX loses $18 when the guy takes the sweater, but gets $100 from his neigbor. He then gives $79 to the guy. At this point, he is up $3. Once he gives $100 to his neighbor, he is then down $97.

The answer is don't take 100$ bills at garage sells, or from someone you met on Craigslist.

I figured total out of pocket cost only because the real value of the sweater isn't determined because a crook paid for it with fake money.

Yep I follow. Math (or logic) fail.

The exchange with the neighbor just a red herring. He gave $100 and got $100, so he's out the $79 plus the value of the sweater. $18 cash out of pocket for that, so $97.

Should've realized that he couldn't have lost more than the amount of the fake bill.

umm.. that sucks, cause the only one who came out losing money is fax, especially if the neighbor is lying. He needs to move to Olathe, where its always sunny.

Well, did he lose the cost of the sweater, or the market value?

But did it happen in mid air? Because that would change things I think.

That assumes that the $100 given back to the neighbor is the same fake $100 bill. That is not clear in the OP.

- $18 for the sweater
+ $100 bill
- $79 given in change
- $100 returned to neighbor

-$97 is your answer
