I have a math problem that I am not sure how to solve.

My question is, based on my current variances and weighted averages, what can you predict that my variance will be based on the new weighted average from June - December

Variance from January to MayConstruction: 83% Variance -

Weighted Average - 36%Materials: 99% Variance -

Overheard: 94% Variance -Weighted Average - 22%

Weighted Average - 42%

TOTAL: 92% - VarianceBased on Projections of spend from June - December here is the change of the Weighted Average

June - December:Construction -

Materials: -Weighted Average - 36%

Overheard:Weighted Average - 38%

-Weighted Average - 26%

SummaryConstruction weighted average stays the same

Materials - Increased 17%

Overheard - Decreased 17%

Thanks a million if anyone can help me with this. I not even sure if you can draw a conclusion.
