70%, the low concentration
\n" ); document.write( "95%, the high concentration
\n" ); document.write( "85%, the mix concentration
\n" ); document.write( "60 gallons , how much of the mix result\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "v, amount of the high concentration antifreeze\r
\n" ); document.write( "
