Ho much water must be evaporated from 120 pounds of solution which is 3% salt to make a solution of 5% salt? I did it exactly the same way it is shown in this link http://www.onlinemathlearning.com/mixtu ... tml#remove (since it's the same problem with different numbers) but I keep getting 40 for the answer instead of the correct answer which is 48, I don't know what am I doing wrong?, please help, thanks this is the equation I used: .97(120)x = .95(120x) x=40

The next equation I get is: .02(120)=.05x Therefore x = (2/5)120=48

A picture is worth.... [attachment=0:282xbv1d]Salt.jpg[/attachment:282xbv1d] 3.6/(120w) = 5/100 w = 48
