Question 8504: how many gallons of salt must be added to 40 gallons of a 20% salt sollution in order to get a 30% sollution Answer by glabow(165) (Show Source):
You can put this solution on YOUR website! How many gallons of salt are already in the 20% solution? If you can figure that out, then you can also figure out how much salt will make a 10% solution.
Would three times that amount make a 30% solution?
