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% discount; if you buy 100 units or more, I’ll give you a 10% discount.
M: Sounds good. OK, I’ll take 100.

W: Can I speak to someone in your sales department? It’s about the order AK3426.

M: Johnson speaking. W: Hello, Mr. Johnson. This is Kate Barnes from North Engineering.
M: Sorry. Mr. Johnson is at a meeting now. But Mr Harris is here. Do you want to talk to him?
W: No, maybe I’ll call later.
