Step-by-step explanation:
The memo says that there will be a meeting at 3:00 PM which is mandatory to attend and the new sales figures will be discussed and appropriate permissions will be taken. So the key idea of this statement is that the meeting which is going to happen is regarding the new sales figures that came in hand, and they will be covered in detail and certain permissions will be taken from the management to better meet the goals in future. There might be some downfall in the sales which provoked a mandatory meeting to be attended by everyone and sales figures will be discussed to might give proper knowledge about the Sales of a specific period.
