What is the recommended stock of coal? What does the woman want to do about the meeting?

M: Jane. shall we go through the inventory then? Let’s start with coal.
F: 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?
F: I think we have enough stock for that.
M: OK, thank you then.

F: Hello, John ..., Rachel Yang here. I’m calling about the project meeting ...
M: ... on the fifteenth of May?
F: Yes... I think that date’s going to be too soon—I still haven’t got the figures I need from the contractor.
M: Do you want to put it off then?
F: Please. I’ll get back to you about alternative dates.
