Hi guys,
I'm trying to find what operation I need to do to find out how much sales I did in a specific month by only using 5 month moving averages of sales. So, if May sales of 36 units roll off the moving average and the moving average goes from 51 in Aug to 66 in Sep. What operation do I need to do to figure out that the sales in September were 100 units if I don't have access to the B column (Sales) and only know the C column of moving averages. I want to figure how my sales for the month of September in this example.
Thank you!
