Tried all sorts of different ways and just can't seem to get this one right. Not by using the example my teacher gave me. Any help would be greatly appreciated. Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! .20x+.10(10-x)=.16*10
.20x+1-.10x=1.6
.10x=1.6-1
.10x=.6
x=.6//.10
x=6 liters of 20% is needed.
Proof:
.20*6+.10(10-6)=1.6
1.2+.10*4=1.6
1.2+.4=1.6
1.6=1.6
