Question 755256: hi can you help with this:
you have two saltwater solutions. one consists of 20% salt,and the other consists of 15% salt.
if you want to add these two together to make 5 gallons of a 17% solution, how much of each solution should you add? Found 2 solutions by stanbon, josgarithmetic:Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! you have two saltwater solutions. one consists of 20% salt,and the other consists of 15% salt.
if you want to add these two together to make 5 gallons of a 17% solution, how much of each solution should you add?
-------
Equation:
salt + salt = salt
0.20x + 0.15(5-x) = 0.17*5
----
20x + 15*5 - 15x = 17*5
5x = 2*5
x = 2 gallons (amt. of 20% solution needed)
5-x = 3 gallons (amt of 15% solution needed)
