Question 1003342
She knows that Solution A is 
20%
salt and Solution B is 
45%
salt. She wants to obtain 
110
ounces of a mixture that is 
25%
salt. How many ounces of each solution should she use?
----
Equation:
salt + salt = salt
0.20x + 0.45(110-x) = 0.25*110
------------------
20x + 45*110 - 45x = 25*110
----
-25x = -10*110
----
x = (2/5)110
--
x = 2*22
x = 44 ounces (amt. of 20% solution needed)
110-44 = 66 ounces (amt. of 45% solution needed)
------------
