Calculating discounts is a common task, whether you're shopping online, comparing sales prices, or just practicing your math skills. This article will clearly explain how to calculate 10 percent off of $50 and provide a simple formula you can use for any percentage discount.

Understanding Percentage Discounts

A percentage discount is a reduction in the original price of an item, expressed as a percentage. For example, a 10% discount means you'll pay 10% less than the original price. To find the final price after the discount, you need to perform two steps: Calculate the discount amount, then subtract it from the original price.

Calculating 10% Off of $50

Here's how to calculate a 10% discount on a $50 item:

Step 1: Find 10% of $50

To find 10% of $50, you can use the following formula:

(Percentage/100) * Original Price = Discount Amount

In this case:

(10/100) * $50 = $5

Therefore, the discount amount is $5.

Step 2: Subtract the Discount from the Original Price

Now, subtract the discount amount ($5) from the original price ($50):

$50 - $5 = $45

The final price after a 10% discount on $50 is $45.

The Quick Formula:

For faster calculations, you can use a shortcut:

Original Price x (1 - Percentage/100) = Final Price

For our example:

$50 x (1 - 10/100) = $50 x 0.9 = $45

This formula directly calculates the final price after the discount, eliminating the need for a separate subtraction step.

Practical Applications:

Understanding percentage discounts is useful in various situations:

• Shopping: Compare prices between stores offering different discounts.
• Sales Tax: Calculate the final price after adding sales tax to a discounted item. (Remember to apply the discount before adding tax!)
• Budgeting: Determine how much you can afford to spend after accounting for discounts.
• Tip Calculations: Adjust the tip percentage based on the pre-discount or post-discount price.

Beyond 10% Off $50: A General Approach

The methods above work for any percentage discount and any original price. Simply substitute the given percentage and price into the formula. For example, to calculate a 25% discount on $75, you would use:

$75 x (1 - 25/100) = $75 x 0.75 = $56.25

Mastering percentage calculations will make you a more savvy shopper and help you manage your finances more effectively. Remember to always double-check your work, especially when dealing with money!
