Beverly Hillbillies comes to mind. Jethro Bodine?

If only it were that easy!

Perhaps a course in economy?

Did your daughter use to work in Accounting for Enron?

It sounds like she's thinking of arbitrage. But I think she made a mistake somewhere down that train of thought, because she won't earn any money exchanging currency unless she's the one working at the bank.

If only it was that easy.

Maybe switch her to a regular high school instead of home schooling?

If its your kid, then its your fault.

She's not entirely wrong; there's a whole industry where they just buy and sell currency for profit (essentially from predicting appreciation or depreciation). Of course, it's not nearly as simple as her idea, and you need a lot of money to make it work...

Dammit tell her the circle. 1 = 13. And 13 = 1. That will snap her back to reality. Don't just insult her mentality!!!
