Let's call the liters of paint added G.
\n" ); document.write( "You start out with 4 liters of paint that is 60 %green and 40 % white.
\n" ); document.write( "4(60/100)=2.4 liters green
\n" ); document.write( "4(40/100)=1.6 liters white
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "I want the percentage of green to be 80% when I add G liters, then,
