Mastering Sales Prices: A Guide to Percentage Discount Calculations

Calculating the sale price after a discount can seem tricky, but it’s really just a matter of breaking down the problem step by step. Let’s tackle a common scenario you might encounter—like if a shirt originally costs $50 and is on sale for 20% off. How do you figure out how much you'll pay? You might be surprised by how simple it is!

First off, let’s talk about percentages. You know what they are; they’re everywhere! From sales signs in stores to your roommate’s share of the pizza. In this case, that pesky 20% off is your key to finding the sale price. But how does it work?

Step 1: Calculate the Discount

Start with the original price of the shirt, which is $50 (easy enough, right?). Now, to find 20% of that, you multiply by 0.20:

[ \text{Discount} = 50 \times 0.20 = 10 ]

Voilà! The discount on your shirt is $10. You'd be saving that much cash, so what’s not to love?

Step 2: Find the Sale Price

Next follows the exciting part. Grab that discount and subtract it from the original price to figure out the sale price. It’s like getting $10 off your favorite snack. Here’s the math:

[ \text{Sale Price} = \text{Original Price} - \text{Discount} = 50 - 10 = 40 ]

So, after applying that snazzy discount, the shirt will cost you just $40! Isn’t that a win?

Why Does This Matter?

Understanding how to apply a percentage discount is crucial, especially for tests like the TEAS. Knowing how to navigate these calculations can save you both time and money. And who doesn’t appreciate knowing how much they can keep in their pocket during a shopping spree?
