In the lab, Austin has two solutions that contain alcohol and is mixing them with each other. Solution A is
\n" ); document.write( "40% alcohol and Solution B is 10% alcohol. He uses 800 milliliters of Solution A. How many milliliters of Solution B does he use, if the resulting mixture is a 20% alcohol solution?
\n" ); document.write( "***
\n" ); document.write( "let x=amt of solution B used
\n" ); document.write( "10%x+40%*800=20%(800+x)
\n" ); document.write( ".10x+320=160+.20x
\n" ); document.write( ".10x=160
\n" ); document.write( "x=1600
\n" ); document.write( "How many milliliters of Solution B does he use? 1600
\n" ); document.write( "
