document.write( " We have    x    mL of the 8% solution, and\r\n" );
document.write( "\r\n" );
document.write( "       (480 - x) mL of the pure alcohol. \r\n" );

document.write( "x mL of the 8% solution contribute 0.08x mL of the pure alcohol to the new mixture\r\n" );

document.write( "Now we write the balance equation for the pure alcohol\r\n" );

document.write( "ANSWER.  460 mL of the 4% solution, and the rest, 480 mL - 460 mL = 20 mL of the pure alcohol should be mixed.\r\n" );
