Math problem.

[john_unai]

I have a 100m3 end product that fully produced from 850kg/m3 density raw material, this will give me end product with density of 850kg/m3.
Now i have 100m3 end product that produced from combination of 70% of raw material with density of 850kg/m3 and 30% of raw material with 450kg/m3 density. what will be my new density of end product? is it 0.7(850) + 0.3(450) = 730kg/m3? I'm losing my basic calculating ability. :stupid::stupid:
