00:03

And here's your shmoop du jour.

00:06

Realdeal25 has been trying to sell a number of jackets on eBay that he advertises as

00:11

"actually worn by the great Charlie Sheen."

00:14

Either no one believes him or no one... cares...

00:16

because they haven't quite flown off the e-shelves as he had hoped.

00:19

They originally went for $80 each... but he is now offering them on sale for 35% off

00:24

in a desperate, last-ditch attempt to rid himself of these things.

00:28

What is the sale price of the jacket?

00:31

Here are the potential answers...

00:36

So this question is a two-parter.

00:38

First we have to calculate the new sales price -- 35% off.

00:42

Old price: $80.

00:44

Discount: 35% of the old price which is... .35 times 80... or 28.

00:50

Now we simply subtract the discount from the old price...

00:53

...and we get $52. Answer C.

00:56

Realdeal25 gets excited when he sees that he finally has an order request...

01:00

...until he realizes that it's some prankster asking for two-and-a-half jackets.
