Question 1046787: A nurse mixes 60 cc of a 50% saline solution with a 10% saline solution to produce a 25% saline solution. How much of the 10% solution should he use? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! Let x be the amount of the 10% solution
MIX:
.50(60) + .10x = .25(60+x)
Solve
.50(60) + .10x = .25(60) + .25x
.25(60) = .15x
.25(60)/.15 = x, the amount of the 10% solution (100cc)
AND
30 + 10 = .25(160) CHECKS!
