\n" ); document.write( "\n" ); document.write( "Mixture result, 2 gallons.
\n" ); document.write( "Mixture concentration wanted, 50%, or 0.50.
\n" ); document.write( "Antifreeze solutions to mix, 70% and 15%, or 0.7 and 0.15.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "TRY to use just one variable.
\n" ); document.write( " Let v = how much of the 70% antifreeze to use.
\n" ); document.write( "This means, 2-v is how much of the 15% antifreeze to use.\r
