Here's your Shmoop dujour, brought to you by Gigantomart.

00:08

It seriously has everything, including a Walmart and a Target.

00:32

We could call our Aunt Flo, and she'd able to answer this for us in about two seconds...

00:37

because that woman knows her way around a sale.

00:40

But we'd rather not get roped into another hour-long discussion about her gout,

00:44

so let's try and go it alone.

00:46

Here's this shirt. It used to cost $X. That's what we're trying to find.

00:51

It went on sale for 35% off the regular price.

00:54

It now costs only $12.

01:07

We know we can write percents as decimals, something that would be really helpful in this instance.

01:11

So we can also express this equation as X - 0.35X = 12.

01:27

Our handy dandy calculator tells us that

01:31

12 over 0.65 equals 18.46,

01:34

which is our answer choice C.

01:37

As in, come help me with my gout.
