Question 1060804
40% salt solution is a suspiciously unrealistic concentration, but here is working with just the algebra, ignoring that:


x, how many gallons of the "40% salt solution" to add


EQUATION TO BEGIN:
{{{(40x+10*8)/(x+8)=30}}}



{{{40x+10*8=30(x+8)}}}

{{{4x+8=3(x+8)}}}

{{{4x+8=3x+24}}}

{{{x+8=24}}}

{{{x=16}}}
