A nurse mixes 70cc of a 60% saline solution with a 30% saline to produce a 36% saline solution. How much of the 30% solution he use?
+36916 Amount of saline of constituents = amount of saline in final solution
.60 (70) + .30 (x) = .36 ( x+70)
42 + .3x = .36x + 25.2
16.8 = .06x
x = 280 cc of 30% solution
