M: Hello, Campus Daily. Advertisement department. This is Mark speaking.
W: Hi. I’m calling to place a couple of ads.
M: Sure. Under what classification?
W: Well, I’d like one to be in the "Roommates Wanted" section.
M: All right. And how would you like your ad to read?
W: 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 the first. 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 sofa and easy chair for sale. Excellent condition, $350 or best offer. Call between 5 and 9 p.m. and ask for Cecilia." Did you get that?
M: Uh-huh. You’ll want your phone number on these, right?
W: Oh, sure. Thanks for reminding me. It’s 555-6792.
M: And how long do you want these ads to run?
W: For a week. I guess, How much would that be?
M: Let’s see—it’s $5.00 a week per line. Your two ads will both take up three lines, so that’s $15 per ad.
