Mastering Discounts: How to Accurately Calculate New Prices

Calculating the price after applying a discount might seem tricky at first, but once you get the hang of it, you’ll wonder why you ever found it confusing! Whether you’re shopping for a new pair of shoes or studying for the Assessment and Learning in Knowledge Spaces (ALEKS) Basic Math Placement Test, being able to swiftly and accurately make these calculations is crucial. Let’s break it down, shall we?

What’s the Deal with Discounts?

Discounts often show up in our daily lives. Maybe you’ve received a “20% off” coupon from your favorite store or seen a sale that makes you feel like a savvy shopper. But here’s the kicker: the true art lies in figuring out what your new price is after that discount is applied. So, let’s simplify the process!

Understanding Percentage Off

Okay, so when you see a discount percentage, it typically means a percentage of the total price is taken off. To know what you’ll actually pay, follow this series of steps:

1. Subtract the percent from 100: This tells you the percentage of the original price that you’ll be retaining. For example, with a 20% discount, you’re keeping 80% of the price.
2. Convert this remaining percentage into a decimal: This is crucial, as it helps make your calculations easier. In our example, 80% becomes 0.80.
3. Multiply this decimal by the original price: Voila! This will give you the new price.

Example Time—Let’s Do Some Math!

Here’s a quick real-world example: Say you have your eye on that amazing jacket that retails for $50 but is having a “20% off” sale. To figure out how much you will actually pay, here's how you would do it:

• Start with 100 - 20 to find how much you’ll pay: 80% is what you’re keeping.
• Convert that to decimal: 80% = 0.80.
• Now multiply: $50 * 0.80 = $40.

So, you’d pay $40 for that fabulous jacket! Easy peasy, right?

Why This Method Works

Now, you might be wondering why you can’t simply subtract the percentage directly from the original price, or convert the price to a percent first. Well, while those ideas seem appealing through logical reasoning, they don’t give you the accurate result needed to determine the new total. The method we discussed ensures you’re keeping the right fraction of that total price, thus getting you the correct new price!
