Heath wants 10l 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 work, . how many liters of pure bleach will heath use? how many liters of the 20% mixture will he use?

To answer the question above, let p be the number of liters of pure bleach so that 10 - p be the number of liters of 20% bleach.

(a) The equation that would best represent the given above is,
                              p(1) + (10 - p)(0.2) = 10(0.9)
(b) Solving the equation above will give us an answer of,
                                p = 8.75
 
                               10 - p = 10 - 8.75 = 1.25
Thus, the answer would be 1.25L. 

For me i think it'll land on blue
