2. heath wants 10 l of a solution that is 90% bleach. he will combine pure bleach with a mixture that is 20% bleach.

(a) write a system of equations to model the problem. use p for the number of liters of pure bleach and m for the number of liters of the mixture that is 20% bleach.

(b) solve the system. show your work. how many liters of pure bleach will heath use? how many liters of the 20% mixture will he use?
