F: May I help you?
M: Yes, I would like to exchange some money.
F: what currency would you like to trade in?
M: I would like to exchange Chinese RMB for American dollars. Do you accept $100 bills?
F: No problem, we can accept any denomination. How much would you like to exchange today?
M: Well, that depends on the rate. How much is the RMB trading at today?
F: It's a shame you didn't come a little earlier, the exchange rate was reset yersterday afternoon. The American dollar is now worth 7.45RMB.
If you would like to sell RMB, we can give you a rate of 7.35.Will that be all right?
M: I guess, here, give me 5,000 RMB worth. I might as well exchange a little extra. Who knows what the exchange rate will be tommorow!
