retarded app store math

tetris goes from $7.99 -> $5.99

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

o_O

more like 25% off (approximately)

these people are blithering idiots

**useless thread, I know**

"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:

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