Would greatly appreciate any help on this finance maths problems I have been trying to solve for days.
The total change in PGM% from 2022 to 2021 is 3%. How can I calculate the relative contribution of each product to this 3% change?
I.e. if I were to add up the PGM% variance of all products, it should sum up to the total % variance.
