dialogue: M: Hey Susan, are you interested in buying some used books for school? You can really save some money that way. W: Well, what do you have? M: Well, let's see. I have a science book called Today's World and I am selling it for 30 dollars. W: 30. That's too expensive for a broken book like that. M: Maybe so, but I bought it for 60 and I wrote a lot of notes in the book that should help you with the class if you could read my writing. W: What else are you selling? M: OK, I have an English writing textbook for 14 dollars, a math book for 23 and a novel for only 7. W: Hmm... M: It's up to you. You know these things go fast. W: OK, I'll take the writing book and the novel. I need both of those for sure. M: No more textbooks? W: Not now. Teachers are always changing their minds about textbooks. M: All right.
