When will they meet? What is the recommended stock of coal?

M: Look, Lynn, I think I have to make our meeting on 18th of October to another day. You see, I have to go out to our branch office in Los Angles to attend the opening ceremony.
W: Em, yes, let me have a look. Mm... How about 21st?
M: 21st... Oh, I have an appointment with my lawyer on that day. Is 22nd OK?
W: No problem. I’ll write it down.

M: Kathy, shall we go through the inventory then?Let’s start with coal.
W: We have about 45 tons. But we are supposed to have 70 tons.
M: So we’ve got too little. We’d better order some more. How about gas?
W: I think we have enough stock for that.
M: OK, thank you then.
