Math Formula for Discount: Simplified Guide with Examples

Discounts are a common part of shopping, whether online or in-store. They help customers save money while businesses attract more buyers. Knowing how to calculate discounts is essential for better budgeting and making smart purchasing decisions. In this article, we'll explore the math formula for discounts, complete with examples and real-life applications.

Understanding Discounts

A discount is a reduction in the price of a product or service. It is typically expressed as a percentage of the original price. Businesses offer discounts during sales, promotions, or for bulk purchases.

The Discount Formula

The formula for calculating a discount is straightforward. The discounted price can be determined as:

\[ \text{Discounted Price} = \text{Original Price} - \text{Discount Amount} \]

The discount amount is calculated as:

\[ \text{Discount Amount} = \text{Original Price} \times \left( \frac{\text{Discount Percentage}}{100} \right) \]

Step-by-Step Calculation

1. Determine the original price: This is the price of the product or service before the discount.
2. Identify the discount percentage: This is the percentage reduction offered.
3. Calculate the discount amount: Multiply the original price by the discount percentage divided by 100.
4. Find the discounted price: Subtract the discount amount from the original price.

Examples

Example 1: Single Item Discount

Problem: A jacket costs $80, and the store is offering a 20% discount. What is the discounted price?

Solution:

Step 1: Calculate the discount amount:

\[ \text{Discount Amount} = 80 \times \left( \frac{20}{100} \right) = 80 \times 0.2 = 16 \]

Step 2: Subtract the discount amount from the original price:

\[ \text{Discounted Price} = 80 - 16 = 64 \]

Discounted Price: $64

Example 2: Bulk Purchase Discount

Problem: A laptop costs $1,200, and the store offers a 10% discount for purchases over $1,000. How much will the customer pay after the discount?

Solution:

Step 1: Calculate the discount amount:

\[ \text{Discount Amount} = 1200 \times \left( \frac{10}{100} \right) = 120 \]

Step 2: Subtract the discount amount from the original price:

\[ \text{Discounted Price} = 1200 - 120 = 1080 \]

Discounted Price: $1,080
