Understanding Percentage Discounts

Before diving into the calculation of 25% off $25, let's establish a solid foundation in understanding percentage discounts. A percentage discount represents a reduction in the original price of an item or service. This reduction is expressed as a percentage of the original price. For instance, a 25% discount means the price is reduced by 25% of its original value.

Key Terminology

• Original Price: The initial price of the item before any discount is applied.
• Discount Percentage: The rate of reduction expressed as a percentage (e.g., 25%).
• Discount Amount: The actual monetary value of the reduction.
• Final Price: The price after the discount has been applied.

Calculating 25% Off of $25: Method 1 - Finding the Discount Amount First

This method involves first calculating the discount amount and then subtracting it from the original price.

Step 1: Convert the percentage to a decimal.

To do this, divide the percentage by 100. So, 25% becomes 25/100 = 0.25

Step 2: Calculate the discount amount.

Multiply the original price by the decimal equivalent of the percentage.

Discount Amount = Original Price × Decimal Equivalent of Percentage

Discount Amount = $25 × 0.25 = $6.25

Step 3: Calculate the final price.

Subtract the discount amount from the original price.

Final Price = Original Price – Discount Amount

Final Price = $25 – $6.25 = $18.75

Therefore, 25% off of $25 is $18.75.

Calculating 25% Off of $25: Method 2 - The Direct Calculation Method

This method involves a slightly shorter calculation by directly finding the final price.

Step 1: Determine the percentage remaining after the discount.

If 25% is discounted, then 100% - 25% = 75% of the original price remains.

Step 2: Convert the remaining percentage to a decimal.

75% becomes 75/100 = 0.75

Step 3: Calculate the final price.

Multiply the original price by the decimal equivalent of the remaining percentage.

Final Price = Original Price × Decimal Equivalent of Remaining Percentage

Final Price = $25 × 0.75 = $18.75

This method also confirms that 25% off of $25 is $18.75.

Applying the Knowledge: Calculating Other Percentage Discounts

The methods described above can be applied to calculate discounts for any percentage and any original price. Let's look at a few examples:

Example 1: 15% off $50

Method 1 (Discount Amount First):

1. Convert 15% to a decimal: 15/100 = 0.15
2. Calculate the discount amount: $50 × 0.15 = $7.50
3. Calculate the final price: $50 – $7.50 = $42.50

Method 2 (Direct Calculation):

1. Determine the remaining percentage: 100% - 15% = 85%
2. Convert 85% to a decimal: 85/100 = 0.85
3. Calculate the final price: $50 × 0.85 = $42.50

Therefore, 15% off $50 is $42.50.

Example 2: 40% off $120

Method 1 (Discount Amount First):

1. Convert 40% to a decimal: 40/100 = 0.40
2. Calculate the discount amount: $120 × 0.40 = $48
3. Calculate the final price: $120 – $48 = $72

Method 2 (Direct Calculation):

1. Determine the remaining percentage: 100% - 40% = 60%
2. Convert 60% to a decimal: 60/100 = 0.60
3. Calculate the final price: $120 × 0.60 = $72

Therefore, 40% off $120 is $72.
