<PRE><B>Question 576674</B>
dilute a 12% salt solution with water to make 36 ounces of 8% salt solution.
 How much water and how much 12% salt solution should she mix together?
;
Let x = amt of 12% solution required
the resulting amt is to be 36 oz, therefore
(36-x) = amt of water required
:
Write an amt of salt equation, the amt of salt remains the same only the percent changes
:
.12x = .08(36)
.12x = 2.88
x = {{{2.88/.12}}}
x = 24 oz of 12% solution
then
36 - 24 = 12 oz of water </PRE>
