Question

Solving a percent mixture problem using a linear equationLaurIn the lab, Chris has two solutions that contain alcohol and is mixing them with each other. He uses 200 milliliters less of Solution A than Solution B. Solution Ais 12% alcohol and Solution B is 18% alcohol. How many milliliters of Solution B does he use, if the resulting mixture has 126 milliliters of pure alcohol?
