Let y = [(1 + α1)x] / (α1 + x) be the equation of the 80-20 curve C1 defined such that the first 21% of products sold correspond to 68% of the annual sales; similarly, let y = [(1 + α2)x] / (α2 + x) be the 80-20 curve C2, obtained by assuming that the first 21% of products correspond to 62% of the annual sales.
Check which of the curves C1 and C2 is a better approximation of the actual trend of the cumulative percentage of the annual sales with respect to the cumulative percentage of the amounts sold.
