document.write( "\"%28480-60%2A5%29%2F%2810-5%29\" = \"180%2F5\" = 36 dimes\r\n" );
document.write( "\r\n" );
document.write( "and  60 - 36 = 24 nickels.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Check.  24*5 + 36*10 = 480 cents.  ! Correct !\r\n" );

\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "Let assume for a minute that ALL 60 coins of the collection are nickels.\r\n" );
document.write( "\r\n" );
document.write( "Then the collection would worth 5*60 = 300 cents.\r\n" );
document.write( "\r\n" );
document.write( "But it is worth by 180 = 480-300 cents more.\r\n" );
document.write( "\r\n" );
document.write( "Why there is this difference ?  - But of course, the difference is due to the fact that I counted 10-cent dimes as 5-cent nickels.\r\n" );
document.write( "\r\n" );
document.write( "So, divide this difference of 180 cents by the difference  10-5 = 5 cents, and you will get the number of dimes.\r\n" );
document.write( "\r\n" );
document.write( "It is exactly what my formula shows at the very beginning of my post.\r\n" );
