To arrive at 2000 liters of 60% saline solution the attendant has to mix a 90% and a 40% saline solution. How many liters of each should be used?
+36916 Sum of ingredients = sum of products
90% solution = x ingredient is .9 x
40% solution = 2000 - x ingredient = .4 (2000-x)
ingredients summed = .6 (2000)
.9x + .4(2000-x) = .6 (2000) solve for x = 90% solution liters to use then 40% is 2000-x liters
