The scientist needs liters of 75 % alcohol solution and liters of 35 % alcohol solution

A scientist needs 480 liters of a 40% alcohol solution. She has available a 75% and a 35% solution. How many liters of the 75% and how many liters of the 35% solutions should she mix to make the 40% solution? Write an equation for the total amount of the solution liters and another equation for the amount of alcohol, and then solve the system to determine how many liters of each alcohol solution was used.

let x represent the number of liters for 75% alcohol solution and y represent the number of liters for 35%

alcohol solution.




The equation that describes the total amount of liters is



The equation that describes the amount of alcohol is


The scientist needs         liters of 75% alcohol solution and         liters of 35% alcohol solution
