Well now, if you ever come across one of them sales and they tell ya that something’s 30 percent off, and the price is $13, you might wonder, how much is that gonna save me? Don’t worry, I’ll tell ya just how to figure it out in a jiffy. Ain’t hard at all, just need a bit of simple math.
First thing you gotta know is that 30 percent is just a way of saying “30 out of every 100 parts.” It’s just a fraction, like cutting a pie into 100 pieces and taking 30 of ‘em. So, let’s start with your $13, cause that’s the price of whatever it is you want to buy.
Now, to figure out 30 percent of $13, here’s what you do. You multiply $13 by 30, like this:
- $13 x 30 = $390
Then, after you get that $390, you gotta divide it by 100, cause 30 percent is just 30 outta 100, right? So, let’s divide:
- $390 ÷ 100 = $3.90
So, you see, 30 percent of $13 is $3.90. That’s how much you’re gonna save! Ain’t that something? Now, you take your original price, $13, and subtract that $3.90 from it, and you get:
- $13 – $3.90 = $9.10
So, after the discount, your new price for that item is gonna be $9.10. Simple as pie, right? You don’t need no fancy calculator for that, just a little bit of math that anyone can do if they’ve got a pencil and paper.
Now, you might ask, “What if I had $20 instead of $13?” Well, it’s the same deal. Just multiply the $20 by 30, divide by 100, and you’ll see you save $6, bringing the price down to $14. You can do it with any price, just follow the same steps.
And if you’re out there shopping online, you might find some of them online calculators that’ll do it for ya. But don’t worry, you can always do it yourself with these easy steps. Save yourself a little bit of trouble, and maybe a little bit of money, too!
So, whether you’re buying a new pair of shoes or a nice shirt, or even some kitchen gadget, just remember: to get the discount, all you gotta do is multiply the original price by the percentage, then divide by 100, and subtract that from the original price. Easy as pie!
