How many dollars do you want to exchange? I want large bills. The office is around the corner. I need to exchange thirty dollars. Where is the exchange office? Thomas arrives at Chicago’s airport. The employee needs information. The office is in Bogota. Sara has a few (some) dollars. The employee is at the window. The businessman needs ninety pesos. John has a short conversation. Can I exchange thirty dollars? The exchange rate is at three pesos (i.e. per dollar). I want large bills, please.
