How to Calculate a Discount and Sale Price | Math with Mr. J?

Imagine you're at a store and your favorite toy is on sale, that means it costs less than usual!

Let’s say your toy normally costs $10, but there's a discount of 20%. That means you pay only part of the full price. To find out how much you’ll save or how much you'll pay, we can do some simple math.

A discount is like getting extra money back from the store, it’s a percentage (like 10%, 20%, or 30%) of the original price that you don’t have to pay.

So if your toy was $10 and there's a 20% discount, you save:

• 20% of $10 = $2

That means you’ll only pay:

• $10 - $2 = $8

The sale price is how much you actually pay after the discount. It's like the new, lower price tag on your toy.

If there’s a 30% discount on a $20 shirt, you save:

• 30% of $20 = $6

Then the sale price becomes:

• $20 - $6 = $14

You can now buy that shirt for just $14, like getting extra candy with your lunch money! Imagine you're at a store and your favorite toy is on sale, that means it costs less than usual!
