\r\n" );
document.write( "Take off these 10 nickels from the collection, for a moment (mentally).\r\n" );
document.write( "Then you can group the remaining coins in sets consisting (one nickel, one dime) each,\r\n" );
document.write( "and the total \"value\" of the remaining coins is 215 - 5*10 = 165 cents.\r\n" );
document.write( "\r\n" );
document.write( "The worth of each group is 10+5 = 15 cents.\r\n" );
