Question 260420: A hospital staff member mixed a 65% disinnfectant solution with a 15% disinfectant solution. How many liters of each were used to make 50 liters of a 37% disfectant solution? Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! .65X+.15(50-X)=.37*50
.65X+7.5-.15X=18.5
.50X=18.5-7.5
.50X=11
X=11/.50
X=22 L. OF 65% SOLUTION IS USED.
50-22=28 L. OF 15% SOLUTION IS USED.
PROOF:
.65*22+.15*28=.37*50
14.3+4.2=18.5
18.5=18.5
