document.write( "8  gallons of 55% acid solution contain 0.55*8 gallons of the pure acid.\r\n" );
document.write( "\r\n" );
document.write( "12 gallons of 65% acid solution contain 0.65*12 gallons of the pure acid.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The mixture contains  0.55*8 + 0.65*12  gallons of the pure acid and has the volume of 8 + 12 = 20 gallons.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore, the concentration under the question is   percents.\r\n" );
