Thank you Answer by scott8148(6628) (Show Source):
You can put this solution on YOUR website! the concentration multiplied by the volume of solution gives the amount of acid
__ the amount should be the same on both sides of the equation
let x="gallons of 4%" __ x(4%)+20(10%)=(20+x)(5%) __ multiplying by 100 clears the percents
