Algebra.Com's Answer #167719 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! This is a NEAT problem. I'm going to say 38 days, because if the pond is 1/4 filled on day 38, then it doubles and becomes half full on day 39, then it doubles again and becomes full on day 40.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Again, congratulation on a REALLY neat problem!!\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "R^2\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Dr. Robert J.
