Simplify Weighted Average Formula
I have a s/s that has the months of the year across the top and below 3
categories for each month and I want a weighted avg for each product. eg: A B C D E F G H I January February March etc. to Dec Days Oil Gas Days OIl Gas Days Oil Gas 6 12 200 4 5 180 7 8 300 formula: =(a1*b1+D1*E1+G1*h1)/(a1+d1+g1) Is there a way to simplify this? Thank in advance for any help. -- ferne
