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?

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
