\n" ); document.write( "--------------
\n" ); document.write( "The melon starts with 0.9*100 = 90 lbs of water and 10 lbs of \"other\".
\n" ); document.write( "--------
\n" ); document.write( "After reduction its \"other\" is 20% of its weight.
\n" ); document.write( "----------
\n" ); document.write( "Let it's weight now be \"x\" lbs.
\n" ); document.write( "EQUATION:
\n" ); document.write( "0.20x = 10 lbs
\n" ); document.write( "x = 10/0.2 = 50 lbs. (it's weight now is 50 lbs.)
