You can put this solution on YOUR website!
10 gallons of 20% antifreeze have \"10+x+20%2F100\" or \"2\" gallons of antifreeze, that's 20% antifreeze, 80% water.
\n" ); document.write( "So you currently have 2 gallons of antifreeze and 8 gallons of water.
\n" ); document.write( "For a 50% solution, you need 50% water and 50% antifreeze.
\n" ); document.write( "You have 8 gallons of water so you need 8 gallons of antifreeze for a 50% solution.
\n" ); document.write( "You have 2 gallons of antifreeze.
\n" ); document.write( "You need 8 gallons of antifreeze.
\n" ); document.write( "You need to add\"8-2+\" gallons of antifreeze.
\n" ); document.write( "Your answer is 6 gallons.
