\n" ); document.write( "-------
\n" ); document.write( "Q + D = 8 (# of coins)
\n" ); document.write( "25Q + 10D = 155 (value)
\n" ); document.write( "===================
\n" ); document.write( "Think about it:
\n" ); document.write( "The # of Q's has to be an odd # < 8.
\n" ); document.write( "7Q = 175 too much
\n" ); document.write( "5Q = 125
\n" ); document.write( "3D = 30
\n" ); document.write( "----------------
\n" ); document.write( "--> $1.55
\n" ); document.write( "
