The description is poor. What sizes are those two \"bottles\"? Given is ONE bottle of pure antifreeze and ONE bottle of 10% antifreeze; making available only TWO bottles. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "On the other hand, the question asks for 8 liters of 77.5% antifreeze. Maybe each bottle is big enough to carry about 4 liters each? The question asks for how many liters, and not how many bottles.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "v, how many liters of the pure antifreeze
\n" ); document.write( "8-v, how many... 10%\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"highlight_green%28%28100%2Av%2B%288-v%2910%29%2F8=77.5%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"100v%2B80-10v=8%2A77.5\"\r
\n" ); document.write( "\n" ); document.write( "\"90v%2B80=8%2A77.5\"\r
\n" ); document.write( "\n" ); document.write( "\"90v=8%2A77.5-80\"\r
\n" ); document.write( "\n" ); document.write( "\"highlight%28v=6%29\"------Six liters of the pure antifreeze
\n" ); document.write( "therefore 2 liters of the 10% antifreeze.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now again, HOW BIG IS EACH BOTTLE?
\n" ); document.write( "
\n" );
