Question 1146493
The example application is very bad!



------------------------------------------
mix A is 12% target material and  mix B is 4% target material. we want to make a 40 ounce  mix that is 9% target material. how much of each A and B mix is needed?
-----------------------------------------


v, amount of the 12% material
M, amount of finished mixture
M=40
T=9
H=12
L=4


{{{Hv+L(M-v)=TM}}}------solve for v.

-

{{{Hv+LM-Lv=TM}}}

{{{(H-L)v+LM=TM}}}

{{{(H-L)v=TM-LM}}}

{{{v=(TM-LM)/(H-L)}}}

{{{highlight(v=M((T-L)/(H-L)))}}}
