Task $1($of $2)$

A company needs to increase the concentration of solution A such that the original solution goes from $10\%A$ to a final solution of $30\%A.$ This will be done by evaporating B$.$ The concentrated solution $($solution with $30\%A)$ sells for $$\frac{100}{L}$ but removing B costs $$\frac{17}{L}.$ If the company has $1,000L$ of the dilute solution, what is the final volume of the concentrated solution, and how much profit does the company make selling it$?$
