DSO in F03B16

I have been asked to verify the DSO number in F03B16.

On page 486 of the A/R manual, it describes the 3 different methods.

　

  The Current Balance Divided by Sales is calculated as follows: DSO = (current A/R balance à number of days inn periods) ÷ Total  invoiced over n number of periods　

What does à mean?

There is a table with sample data on page 486 of the A/R manual.

　

　

Where does the sales amount and period end balance come from?

　

　

　

Period	Sales Amount	Period End Balance	Period Days
January	7570	10825	31
