Question 1118927
.
<U>In form of two equations</U> it is


<pre>
        x +     y = 125            (1)     (milliliters; total volume)
    0.21x + 0.36y = 0.33*125       (2)     (x= volume of the drink A;  y = volume of the drink B).


    Solve by any method.
</pre>


or <U>in form of ONE equation</U>


<pre>
    0.21x + 0.36*(125-x) = 0.33*125.


    Simplify and solve this single equation for single unknown.


    0.21x + 0.36*125 - 0.36x = 0.33*125

    -0.15x = 0.33*125 - 0.36*125

    -0.15x = -0.03*125  ====>  x = {{{(0.03*125)/0.15}}} = 25.


<U>Answer</U>.  25 mL of the drink A should be mixed with  (125-25) = 100 mL of the drink B.
