You open the envelope, and you have a certain amount of money. You will AT LEAST come away with half of that if you decide to switch. Do a little math, and you end up with a "tripple or nothing" scenario.
For example you open it up and there's $1,500. You can then wager half of that, $750, that you'll win an additional $2,250. ($750 + $2,250 = $3000.) That $2,250 is three times the "original" $750.
Do it once and you have that single 50/50 chance. It's all about your risk/reward comfort level. (If $1500 will pay off the mob who's out to get you, but $750 won't cut it, the answer is obvious. If yesterday your paid cash for you Carrera GT, you might as well go for the switch since you're risking basically nothing.) Do it enough however and the odds are in your favor - you'll eventually come out ahead, by 25% I think is the amount.

The contestant would be trading their envelope, which contains money, for the open envelope, which is empty.
Rethink/Rephrase:
The contestant should trade their "$200" envelope, which is open and empty, for the unopened envelope with whatever amount it contains.
(Damn, envelope is hard to type!)
