For his chemistry experiment, martin needs 3 liters of a 40% alcohol solution. the lab has two containers, one with 20% alcohol solution and the other with 50% alcohol solution.
a.) write a system of linear equations that you can use to determine how many liters of each type of alcohol solution martin should combine to get 3 liters of a 40% alcohol solution. be sure to define your variables.
b.) solve the system and determine how many liters of each type of alcohol solution martin should combine. show all your work.
