W: Hi. I’m calling to place a couple of ads.
M: Sure. Under what classification?
W: Well, I want one in the "Roommate Wanted" section.
M: All right. And how would you like that to read?
W: Ok, it should read female roommate wanted for pleasant, sunny two bedroom apartment on Elliewood Avenue, three blocks from campus. Share rent and utilities. Available September 1. Call between 5 and 9 P.M. and ask for Cecilia.
M: Fine. And what about your other ad?
W: That one I’d like under "Merchandise for Sale", and I’d like it to read "Matching blue and white sofa and easy chair, excellent condition, $350 or best offer. Call between 5 and 9 P.M. and ask for Cecilia." Did you get all that?
M: Uh-huh. You’ll want your phone numbers on these, right?
W: Oh, sure. Thanks for reminding me, it’s 5556972.
M: And how long do you want these ads to run?
W: For a week, I suppose. How much would that be?
M: It’s five dollars a week per line. Each of your ads will take up three lines, so that’s $15 per ad.
