Let D = number of dimes and N=number of nickels.\r
\n" ); document.write( "\n" ); document.write( "D=2N\r
\n" ); document.write( "\n" ); document.write( "D+2N=8\r
\n" ); document.write( "\n" ); document.write( "D+D=8
\n" ); document.write( "2D=8
\n" ); document.write( "D=4\r
\n" ); document.write( "\n" ); document.write( "So the number of dimes represents $4. So this must mean there are 40 dimes ($4/$0.10) and 80 nickels ($4/$0.05). \r
\n" ); document.write( "\n" ); document.write( "
