-a mixture that contains an equal amount of 2% acid solution and 3% acid solution

-a mixture that contains 3 times more 2% acid solution than 3% acid solution

**Steve**, Friday, December 30, 2011 at 12:08amequal amounts: 2.5%

if 3% solution is x times the 2% solution, then if the resulting concentration is y%,

.02 + .03x = (1+x)*y

You can see that if x=1, y=.05/2 = .025 = 2.5%

If x = 3, .11 = 4y, so y = .11/4 = .0275 = 2.75%

Makes sense, since the new concentration is 3/4 of the way from 2% to 3%.

**Steve**, Friday, December 30, 2011 at 4:35pmGood thing you reposted it. I misread the problem, and solved it for having 3 times as much 3% as 2%. See bobpursley's solution for the correct answer.

Having read my algebra carefully, though, you should have been able to do it right.
