In the lab, Eric has two solutions that contain alcohol and is mixing them with each other. He uses 3 times as much Solution A as Solution B. Solution A is 20% alcohol and Solution B is 14% alcohol. How many milliliters of Solution B does he use, if the resulting mixture has 518 milliliters of pure alcohol?
