document.write( "\r\n" );
document.write( "Let number of nickels be N\r\n" );

document.write( "Value of dimes:    .1(N + 5) = .1N + .5\r\n" );
document.write( "Value of quarters:.25(N + 6) = .25N + 1.5 \r\n" );

document.write( "As total value is 6.80, we get:  .05N + .1N + .5 + .25N + 1.5 = 6.8\r\n" );
