A jar of dimes and quarters contains $15.25. There are 103 \r\n" );
document.write( "coins in all. How many quarters in the jar?\r\n" );
document.write( "thanx\r\n" );
document.write( "\r\n" );
document.write( "Let D = the number of dimes and Q be the number of quarters\r\n" );
document.write( "\r\n" );
document.write( ">>...There are 103 coins in all...<<\r\n" );
document.write( "\r\n" );
document.write( "Therefore D + Q = 103\r\n" );
document.write( "\r\n" );
document.write( ">>...A jar of dimes and quarters contains $15.25...<<\r\n" );
document.write( "\r\n" );
document.write( "The money which the D dimes is worth is $.10 times D or .10D\r\n" );
document.write( "\r\n" );
document.write( "The money which the Q quarters is worth is $.25 times Q or .25D\r\n" );
document.write( "\r\n" );
document.write( "So .10D + .25D = 15.25\r\n" );
document.write( "\r\n" );
document.write( "We have this system:\r\n" );
document.write( "\r\n" );
document.write( "   D +    Q = 103\r\n" );
document.write( ".10D + .25D = 15.25\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Can you solve that system?  If not post again.\r\n" );
document.write( "\r\n" );
document.write( "Answer 70 dimes and 33 quarters\r\n" );
