\r\n" );
document.write( "Let Q be the number of quarters.\r\n" );
document.write( "\r\n" );
document.write( "Then the number of nickels is (16-Q).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The quarters contribute 25Q      cents to the total.\r\n" );
document.write( "\r\n" );
document.write( "The nickels  contribute 5*(16-Q) cents to the total.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The total value equation is\r\n" );
document.write( "\r\n" );
document.write( "25Q + 5*(16-Q) = 340  cents,\r\n" );
document.write( "\r\n" );
document.write( "25Q + 80 - 5Q = 340,\r\n" );
document.write( "\r\n" );
document.write( "20Q = 340 - 80 = 260  ====>  Q =  = 13.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  13 quarters and 16-13 = 3 nickels.\r\n" );
