I have a science book called, Today's World, and I'm selling it for thirty dollars. Ashley: Thirty? That's a little expensive for a beat-up book like that. Carl: Maybe so, but I bought it for sixty. Plus, I wrote a lot of notes in the book that should help you with the class ... if you could read my writing. Ashley: What else are you selling? Carl: Okay, I have English writing textbook for fourteen dollars, a math book for twenty-three, and a novel for only seven bucks. Ashley: Uh, Hmmm. Carl: It's up to you.
