The Percentage Decrease in the Price of a Shirt

The concept of percentage decrease is fundamental in various fields, including business, economics, and consumer affairs. This article explains how to calculate the percentage decrease in the price of an item, specifically a shirt, from an original price to a new price. Let's walk through a practical example to understand the process step by step.

Understanding the Percentage Decrease Calculation

To find the percentage decrease in the price of the shirt, we follow a simple formula:

Formula: Percentage Decrease

Percentage Decrease left( frac{Original Price - New Price}{Original Price} right) times 100

In this scenario:

Original Price $40 New Price $28

Step-by-Step Calculation

1. Subtract the New Price from the Original Price to find the price reduction:

Price Reduction Original Price - New Price

2. Divide the price reduction by the Original Price to find the fractional decrease:

Fractional Decrease frac{Original Price - New Price}{Original Price}

3. Convert the fractional decrease to a percentage by multiplying by 100:

Percentage Decrease left( frac{Original Price - New Price}{Original Price} right) times 100

Applying the Formula

Substitute the values into the formula: Percentage Decrease left( frac{40 - 28}{40} right) times 100 Simplify the expression inside the parentheses: Percentage Decrease left( frac{12}{40} right) times 100 Simplify further: Percentage Decrease 0.3 times 100 The result is: Percentage Decrease 30

Therefore, the price of the shirt was reduced by 30%.

Practical Applications and Insights

This method not only helps in calculating discounts but also in understanding economic phenomena such as inflation, sale prices, or even stock market fluctuations. Understanding how to calculate percentage decrease is a valuable skill for making informed financial decisions.

For example:

Calculating the original selling price based on the desired profit margin. Understanding the true profit percentage when offering discounts on items. Tracking price reductions over time for inventory management and pricing strategies.

Final Example

Consider a scenario where the original price of an item is $40, and it is currently on sale for $28.

Find the price reduction: 40 - 28 12 Divide the price reduction by the original price: 12 ÷ 40 0.30 Convert the fractional decrease to a percentage: 0.30 times 100 30%

Thus, the shirt is on sale at a 30% discount.

Conclusion

Understanding how to calculate percentage decrease is essential for evaluating various financial and business scenarios. By breaking down the process into simple steps, we can apply this knowledge to a wide range of practical situations, from everyday shopping to complex business decisions.
