N=D+4
\n" ); document.write( ".10D+.05N=1.25
\n" ); document.write( ".10D+.05(D+4)=1.25
\n" ); document.write( ".10D+.05D+.20=1.25
\n" ); document.write( ".15D=1.25-20
\n" ); document.write( ".15D=1.05
\n" ); document.write( "D=1.05/.15
\n" ); document.write( "D=7 NUMBER OF DIMES.
\n" ); document.write( "N=7+4=1 NUMBER OF NICKELS.
