Question 1088113: A pharmacist wishes to mix a solution that is 77% Minoxidil. She has on hand 100100 ml of a 11% solution and wishes to add some 99% solution to obtain the desired 77% solution. How much 99% solution should she add Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Let n be the amount of 99% solution. Then:
.11(100)+.99(n)=.77(100+n)
11+.99n=77+.77n
.22n=66
n=66/.22
