Question 906607: 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
65% salt. She wants to obtain 170 ounces of a mixture that is 55%salt. How many ounces of each solution should she use? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! a+b=170,
0.4*a+0.65*b=0.55*170
a=170-b
0.4*(170-b)+0.65*b=93.5
68-0.4b+0.65*b=93.5
0.25*b=25.5
b=102
a=170-b
a=68 oz. at 40%
b=102 oz. at 65%
check
0.4*68+0.65*102=0.55*170
27.2+66.3=93.5
93.5=93.5
ok
