A:Good afternoon, miss. May I help you? B:Yes, please. I have a lot of things to do for my tourists. Firstly. I would like to mail this letter to the United States. What's the postage? A:That's 18 grams, so it will cost you one yuan and 60 cents. Anything else? B:Yes, How much will these postcards cost?
A:Are they all going to the U.S.? B:Yes. A:They cost 65 cents each. Let's see, you have four of them here, right?
B:Right. But I'd like to buy six more as well. A:OK. Anything else?
