How many company catalogues are left?

W: We only have 12 company catalogues left in the inventory room. We’ll have to hand them out at the briefing for job applicants the day after tomorrow. So far we have 20 applicants and expecting more. Probably we have to prepare 15 more to be safe.
M: Even if we order them from the supplier now, it will take at least a week. I’ m afraid we are in a difficult position.
W: I’ m sorry, but I should have checked it much earlier. What about another branch?
M: What a good idea! I’ll call Susie in Chicago to ask her to send some more. I’ m sure they have some extra catalogues.
