Sue...you thanked me for helping to simplify a concept. I believe I showed you a simplified way of how to get around it, if you think you can get away with it. Among my many other weird adventures I've done business in Hong Kong. I'd be surprised if your teacher thought my methods were sound. I honestly don't know where I explained the nuances of the concept at all. Ergo, what did I simplify?
The point here is to learn to think out of the box. You got some good responses. You also got ragged, which is exactly what would happen to anyone going to school putting up something for grabs had they asked the questions at the dorm or the bar. You got some answers, and got picked on for fun. Life is. Don't get so personal.
As this is an elective, why take something you have to devote this kind of energy to? Devote the brain drain to your core subjects and take remedial basketweaving for a filler. I still can't get how you are taking International Business without at least a fundamentals of business course for background.
Just my $.02, but I try to be practical.
