How much of a saline solution that is 20% saline should be mixed with 200 ounces of a saline solution that is 50% saline to get a solution that is 30% saline? State your solution in a complete sentence.
==========
Equation::
saline + saline = total saline
0.20x + 0.50*200 = 0.30(x+200)
-----
Multiply thru by 10 to get::
2x + 1000 = 3x+ 600
x = 400 ounces (Amount of 20% solution to add)
