What is 20 Percent Off 75 Dollars? A Comprehensive Guide to Percentage Discounts

Calculating discounts is a crucial skill in everyday life, from shopping for groceries to making big-ticket purchases. Understanding how to determine the final price after a percentage discount is essential for smart financial decisions. This comprehensive guide will walk you through calculating 20% off $75, exploring different methods, and offering valuable insights into percentage calculations in general.

Understanding Percentage Discounts

Before diving into the specifics of a 20% discount on $75, let's clarify the concept of percentage discounts. A percentage discount represents a reduction in the original price of an item or service. It's expressed as a fraction of 100. For instance, a 20% discount means a reduction of 20 out of every 100 units.

Key Terms:

• Original Price: The initial price of the item before any discount is applied.
• Discount Percentage: The percentage reduction offered on the original price.
• Discount Amount: The actual amount of money saved due to the discount.
• Final Price: The price after the discount is applied; this is what you'll pay.

Method 1: Calculating the Discount Amount First

This is a straightforward two-step method. First, calculate the discount amount, and then subtract it from the original price.

Step 1: Calculate the Discount Amount

To find 20% of $75, we can use the following formula:

(Discount Percentage / 100) * Original Price = Discount Amount

(20 / 100) * $75 = $15

Therefore, the discount amount is $15.

Step 2: Subtract the Discount from the Original Price

Subtract the discount amount ($15) from the original price ($75):

$75 - $15 = $60

Therefore, 20% off $75 is $60.

Method 2: Calculating the Final Price Directly

This method is more efficient and involves finding the remaining percentage after the discount.

Step 1: Determine the Remaining Percentage

If we're getting a 20% discount, then the remaining percentage we'll pay is:

100% - 20% = 80%

Step 2: Calculate the Final Price

To calculate the final price directly, we multiply the original price by the remaining percentage:

(80 / 100) * $75 = $60

Therefore, 20% off $75 is $60. This method avoids the extra step of calculating the discount separately.

Applying Percentage Discounts to Different Scenarios

The methods above can be applied to various situations involving percentage discounts. Let's explore a few examples:

Example 1: Sales Tax

Imagine you bought an item for $60 (after the 20% discount) and need to add sales tax. Let's assume the sales tax is 6%.

First, calculate the sales tax amount:

(6 / 100) * $60 = $3.60

Then, add the sales tax to the discounted price:

$60 + $3.60 = $63.60

The final price including sales tax would be $63.60.

Example 2: Multiple Discounts

Sometimes, you might encounter multiple discounts, like a 20% off sale followed by an additional 10% off for VIP members. In such cases, you'd apply the discounts sequentially.

First, apply the 20% discount:

$75 - ($75 * 0.20) = $60

Then, apply the 10% discount to the already discounted price:

$60 - ($60 * 0.10) = $54

The final price after both discounts would be $54. Note: It's crucial to apply the discounts sequentially, not just add them together (20% + 10% = 30%). Adding percentages directly isn't accurate for multiple discounts.

Example 3: Discounts and Coupons

You might have a coupon for an additional $5 off after the 20% discount.

Start with the discounted price:

$75 - ($75 * 0.20) = $60

Then subtract the coupon value:

$60 - $5 = $55

The final price would be $55. Coupons are usually applied after percentage discounts.

Using Calculators and Spreadsheets for Efficiency

For more complex scenarios or frequent calculations, using a calculator or spreadsheet software is highly recommended. Calculators have percentage functions that simplify the process significantly. Spreadsheets like Microsoft Excel or Google Sheets allow you to set up formulas to automatically calculate discounts for multiple items or changing discount percentages.
