    Exclamation solving tables

    can anyone help me set up a table for this problem, and then solve it?

    a lab technician has one solution that is 60% chlorinated and another that is 40% chlorinated. How much of each solution is needed to make a 100L solution that is 50% chlorine?

    Hello, Heather!

    A lab tech has a solution that is 60% chlorine and another that is 40% chlorine.
    How much of each solution is needed to make a 100L solution that is 50% chlorine?

    . . \begin{array}{|c|c|c|c|}<br />
& \text{Liters} & \text{Percent} & \text{Chlorine} \\ \hline<br />
A & x & 0.60 & 0.6x \\<br />
B & 100-x & 0.40 & 0.4(100-x) \\ \hline<br />
\text{Mix} & 100 & 0.50 & 0.5(100) \end{array}


    The equation is in the last column: . 0.6x + 0.4(100-x) \;=\;50

    Got it?
