tricky but the only reasoning for me is this:
the 2nd stimulus says: Facebook's revenue for the Mar'12 quarter 8so here we have a forecast of revenue) if the year over year
growth for that quarter is at 50%.
This means that the next year the growth should be (for instance of 100%) the double BUT we have the 50%
so: in march 2011 we have 700 in $ + 50 % of 7 we have 3.5 ---> 7 + 3.5 = 10.5
Only 1.1 fit the bill.
Hope this helps. I do not see other expalantions
