q quarters and d dimes;
\n" ); document.write( "\"0.25q%2B0.1d=2.80\"
\n" ); document.write( "\"5q%2B2d=56\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Friend says, \"q=8%2Bd\".
\n" ); document.write( "Check how this is.
\n" ); document.write( "\"5%288%2Bd%29%2B2d=56\"
\n" ); document.write( "\"40%2B5d%2B2d=56\"
\n" ); document.write( "\"7d=56-40\"
\n" ); document.write( "\"7d=16\"
\n" ); document.write( "\"d=16%2F7\"-----------NOT a whole number.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The friend is wrong. The idea leads to d number of dimes being nonwhole.
