<PRE><B>Question 1047306</B>
 Heather has two solutions that contain alcohol and is mixing them with each other. She uses 500 milliliters less of Solution A than Solution B. 
Solution A is 17% alcohol and Solution B is 11% alcohol. 
How many milliliters of Solution A does she use, if the resulting mixture has 
167 milliliters of pure alcohol?
------------
 B - A = 500
0.11B + 0.17A = 1*167
----------------------
11B - 11A = 11*500
11B + 17A = 100*167
-----------------
6A = 22200
A = 3700 ml

Cheers,
Stan H.
