Question 1163087
-------------------------------------------------------------
want to obtain a liter of a 12% salt solution, mixing X milliliters of an 8% salt solution with Y milliliters of another 18% salt solution, what will be the number of milliliters in the new solution?
------------------------------------------------------------


The answer was already given in the problem description.  One Liter must be the amount of volume in the finished solution. 



--------------------------------------------------------------
want to obtain V liters of a T% salt solution, mixing x milliliters of an L% salt solution with y milliliters of another H% salt solution, what will be the number of liters <s>in the new</s> of each solution to use?
-------------------------------------------------------------


y of the H% material
V-y of the L% material


{{{Hy+L(V-y)=TV}}}
-
{{{Hy+LV-Ly=TV}}}
{{{Hy-Ly+LV=TV}}}
{{{(H-L)y=TV-LV}}}
{{{y=(TV-LV)/(H-L)}}}

{{{highlight(y=V((T-L)/(H-L)))}}}, and you can find the other material quantity.

Decide if you want to convert to milliliters of stay in liters.
