Heath needs to end up with 10L of solution,

of which 9L is bleach. So let m = liters of 20%

solution needed. Then .20m liters of that are bleach.

He must then add p liters of bleach to make

a total of 10 L. That is, p + m = 10. So the system is

m + p = 10, .20m + p = 9. Solving,

<span>m = 1.25 L 20% solution, and thus p = 8.75 L bleach.</span>
