<PRE><B>Question 855231</B>
1 solution is 23 acid and another solution is 57 percent acid how many milliliters of each should be mixed to obtain 34 millimeters of a solution that is 32 percent acid
------
Quantity Eq:: t + f = 34 ml
Acid Eq:: 0.23t + 0.57f = 0.32*34
---------------------------------------
Modify for elimination:
23t + 23f = 23*34
23t + 57f = 32*34
------------------------
34f = 9*34
---
f = 9 ml (amt. of 57% solution needed)
-----------------------
t = 34-9 = 25 ml (amt. of 23% solution needed)
