How much water should be added to 1 gallon of pure antifreeze to obtain
\n" ); document.write( " a solution that is 60% antifreeze?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of water required to accomplish this
\n" ); document.write( ":
\n" ); document.write( "1.0(1) = .6(x+1)
\n" ); document.write( "1 = .6x + .6
\n" ); document.write( "1 - .6 = .6x
\n" ); document.write( ".4 = .6x
\n" ); document.write( "x = \".4%2F.6\"
\n" ); document.write( "x = \"2%2F3\" gallon of water required
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the original equation (use .67 for 2/3 gal)
\n" ); document.write( "1 = .6(.67+1)
\n" ); document.write( "1 = .6(1.67)
\n" ); document.write( "1 = 1.00 \n" ); document.write( "
\n" );
