- Math Mixture Word Problem -
**Steve**, Sunday, February 9, 2014 at 9:18pmthe amount of saline must be the same before and after mixing:

.05(1) + 0(x) = .02(1+x)

.02x = .03

x = 1.5

check:

5% of 1L = .05L saline

2% of 2.5L = .05L saline

or, you can say that since you want 2/5 the concentration, you need 5/2 the original volume, or 2.5L
