\r\n" );
document.write( "Indeed, according to the problem, we can group the coins in sets, \r\n" );
document.write( "each containing 5 nickels and one dime.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Each such set is worth 5*5 + 10 = 35 cents.\r\n" );
document.write( "\r\n" );
document.write( "Hence, the number of sets is   = 7.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the coin collector has 7 dimes and 5*7 = 35 nickels.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.  7*10 + 35*5 = 245 cents = $2.45.   ! correct !\r\n" );
