Question 468619: A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 40% salt and Solution B is 90% salt. She wants to obtain 130 ounces of a mixture that is 60% salt. How many ounces of each solution should she use? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! 130x.6=78
a+b=130
.40a+.9b=78
4a+9b=780
4a+4b=520
5b=260
b=52
a=78
She needs 78 oz. of solution A and 52 oz. of solution B..
