200
Hey, man, I need to borrow twenty bucks. Okay? I have to buy this stupid book for my music class. It's about lullabies or something. I can't believe a book of lullabies is so expensive. And I can't believe my instructor is making us buy this book. I know. I should've used the twenty bucks I had yesterday to buy the book, but I forgot about it, and, besides, I really wanted that new CD. So, come on, be cool and lend me the money. I'll pay you back on my next payday.
What is the purpose?
What is to persuade the audience to loan him $20?
