Question 1088996
.
<pre>
0.12x + 0.27*15 = 0.24*(x+15)  ====>

0.12x + 0.27*15 = 0.24x + 0.24*15  ====>  

0.12x - 0.24x = 0.24*15 - 0.27*15  ====>

-0.12x = -0.03*15  ====>


x = {{{(-0.03*15)/(-0.12)}}} = 3.75.


<U>Answer</U>.  3.75 liters of the 12% solution must be mixed with 15 liters of the 27% solution to get 0.24% solution.
