N+D=28 OR N=28-D
\n" ); document.write( ".05N+.10D=2.60
\n" ); document.write( ".05(28-D)+.10D=2.60
\n" ); document.write( "1.40-.05D+.10D=2.60
\n" ); document.write( ".05D=2.60-1.40
\n" ); document.write( ".05D=1.20
\n" ); document.write( "D=1.20/.05
\n" ); document.write( "D=24 DIMES.
\n" ); document.write( "N=28-24
\n" ); document.write( "N=4 NICKELS.
