\n" ); document.write( "---------------------
\n" ); document.write( "I'll try 40 dimes and 10 quarters
\n" ); document.write( "\"+.1%2A40+%2B+.25%2A10+=+6.5+\" $6.50
\n" ); document.write( "--------------------------------
\n" ); document.write( "I'll try 42 dimes and 8 quarters
\n" ); document.write( "\"+.1%2A42+%2B+.25%2A8+=+6.2+\" $6.20
\n" ); document.write( "----------------------------------
\n" ); document.write( "I'll try 43 dimes and 7 quarters
\n" ); document.write( "\"+.1%2A43+%2B+.25%2A7+=+6.05+\" $6.05
\n" ); document.write( "----------------------------------
\n" ); document.write( "I'll replace one of the dimes with a nickel
\n" ); document.write( "\"+.1%2A42+%2B+.05%2A1+%2B+.25%2A7+=+6+\" $6.00 -OK

\n" ); document.write( "---------------------------
\n" ); document.write( "I'll try 16 quarters and 34 nickels
