How much should the man pay?

W: Here’s the stand.
M: Ah, yes. Hmm, how much is this chair? W: It’s $20.
M: Could you give me a discount?
W: A discount? Well, it depends on the size of the order. If you buy 50 units, I’ll give you a 5% discounts if you buy 100 units or more, I’ll give you a 10% discount.
M: Sounds good. OK, I’ll take 100.

M: Good morning. Miss Rossi. How was your trip to Europe?
W: Very interesting but tiring.
M: You have been to several countries, right?
W: Yes. It’s realty a full schedule. On Tuesday I was in France. On Wednesday I went to Austria for a conference, and on Thursday I had to go back to France for the exhibition, and then on Friday I went to Germany for the new product show. I hardly have a break during this trip.
