\r\n" );
document.write( "Let D be the number of dimes.\r\n" );
document.write( "\r\n" );
document.write( "Then the number of nickels is (51-D).\r\n" );
document.write( "\r\n" );
document.write( "D dimes contribute 10*D cents to the total.\r\n" );
document.write( "\r\n" );
document.write( "(51-D) nickels contribute 5*(51-D) cents to the total.\r\n" );
document.write( "\r\n" );
document.write( "The \"value\" equation is\r\n" );
document.write( "\r\n" );
document.write( "5*(51-D) + 10*D = 355 cents.\r\n" );
document.write( "\r\n" );
document.write( "Simplify and solve it for D.\r\n" );
