I just need help with the formula of how to figure out this problem I am not sure where to begin, Thanks! Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! percent ----------------quantity
Saline 2 ----------------50
Saline 20 ----------------x
Total 10 ----------------50+x
...
2*50+20*x=10(50+x)
100+20x=500+10x
20x-10x =500-100
10x=400
/10
x=40 ounces of 20% Saline
