Weighted Averages in Excel

[Guest]

Hi,

I have four numbers in excel, each in a different cell. I need a fifth cell
to show the average of the first four.

No problem normally, but I need to give each figure a different weighting.
So figures 1 & 2 must each be worth 17% of the average, figures 3 and 4 must
each be worth 33% of the average.

Can anyone tell me what formula I need to achieve this?

Thanks

Karl

=17%*(A1+B1)+33%*(C1+D1)
