1. In the lab, Deon has two solutions that contain alcohol and is mixing them with each other. Solution A is 40% alcohol and Solution B is 12% alcohol. He uses 1000 milliliters of Solution A. How many milliliters of Solution B does he use, if the resulting mixture is a 32% alcohol solution?

I need help with this one please
