tetris goes from \$7.99 -> \$5.99

in the app store it says "For a limited time, Tetris will sell for 40% off."

more like 25% off (approximately)

these people are blithering idiots

... But the original price was \$10... and subtract \$4 and that's 40% off.

Hey I don't think it's fair to call him retarded. It was just a mistake.

"You want to buy something that costs \$9.99 (from this to \$7.99 to now \$5.99), and it's on sale for 40% off. What is the item's sale price?

First, convert the 40% to a real mathematical number. For percents, this is always done by dividing the 40% by 100%, or 40% / 100% = 0.400.

Second, find out what 40% of \$9.99 is. This is the amount of the sale discount. This is always found by mulitplying 0.400 by the item's cost \$9.99, like this:

0.400 x \$9.99 = \$ 4.00.

So for this sale, you'll save \$ 4.00 on this item.

This means, the cost of the item to you is
\$9.99 - \$ 4.00 = \$ 5.99.

Alternatively, you can think about it this way. The item is 40% off. This means you'll pay 60.000% of the total cost (100% - 40% = 60.000%).

Now what's 60.000% of the total cost?
0.600 x \$9.99 = \$5.99.
Just like the result above, the sale price on the item is \$5.99."

By the way, I'm not a math genius so I didn't do any of this. I got it from here:
http://www.webmath.com/cgi-bin/sale.cgi?param0=7.99&param1=40&back=sale.html

The bold means I put it there and it wasn't there in the first place.

I agree as well, shallow and pedantic...
