Hello all, I'm a newcomer here, but I'm trying to do an analysis and am having trouble coming up with an equation/calculation that I feel confident addresses what I need...(adsbygoogle = window.adsbygoogle || []).push({});

Assuming in period one that [ A1 * B1 = C1 ].

during the second period, A1 and B1 have both changed (increased/decreased) to A2 and B2, respectively, so that now [ A2 * B2 = C2 ].

My problem is - how can I quantify how much of the change in C was attributable to both the change in A and the change in B? Said another way, the change in A accounted for, or drove, what percentage of C's change, and the same for B.

Does that make sense?

Thanks in advance for any responses - any help would be greatly appreciated.

Lewis
