You can put this solution on YOUR website!
Let A be 100, for the sake of easiness.
\n" ); document.write( "10% of 100 is 10
\n" ); document.write( "5% of 100 is 5. 5% \"again\" is 5% of 95, or 4.75. Total 9.75
\n" ); document.write( ".
\n" ); document.write( "You've probably seen this in department stores. \"Extra 50% off already reduced merchandise.\" Wow, a beautiful dress for $100 marked down to $50. Shouldn't this be free? No, it is 50% off the already discounted price of $50, or 75% off, not 100%. Still a good deal :-).
