[originaltext]W: I’d like to exchange this green tablecloth that I bought last

W: I’d like to exchange this green tablecloth that I bought last week for the red one.
M: Let’s see now. The red costs only $10.95, and the green one was 15.
Approximately how much money does the clerk owe the woman?

M: I have this camera here that I bought about 12 months ago. But it suddenly doesn’t work.
W: Let me have a look at your sales slip, I am sorry, sir. Your warranty’s expired.
What does the woman mean?
