Hi,
In a situation of talking about a company's or a small enterprise's (a store's?) monthly (or any periodic time) bottom line or performance level, I think I have encountered the plural words like "profits", "incomes", and "figures" used in the wording of some kind of descriptive report.  Are they correct? Why not use singular words like "profit" and "figure" when it seems logical that when a company counts how much it has made at the end of some period, a single number indicating a bottom line would likely to surface, not two bottom lines.  

A possible wording in *** Company's monthly report?

For the month of Febuary, our profits/profit figures/incomes rose 10 percent over the same month last year.
