\r\n" );
document.write( "Let D be the number of dimes.\r\n" );
document.write( "\r\n" );
document.write( "Then the number of quarters is (110-D).\r\n" );
document.write( "\r\n" );
document.write( "The \"value equation\" is\r\n" );
document.write( "\r\n" );
document.write( "10D + 25*(110-D) = 2000.\r\n" );
document.write( "\r\n" );
document.write( "Simplify and solve for D:\r\n" );
document.write( "\r\n" );
document.write( "10D + 2750 - 25D = 2000,\r\n" );

document.write( "Answer.  There are 50 dimes and 110-50 = 60 quarters in the collection.\r\n" );
