Introduction

When shopping, it's common to come across sales and discounts that can significantly reduce the price of an item. In this scenario, a jacket is on sale for $15 off, and an additional 20% discount is applied to all purchases. To determine the final price of the jacket, we need to understand how these discounts affect the original price. In this article, we'll explore the concept of discounts and how to calculate the final price of the jacket.

Understanding Discounts

A discount is a reduction in the price of an item. In this case, the jacket is on sale for $15 off, which means the price is reduced by $15. Additionally, a 20% discount is applied to all purchases, which means the price is reduced by 20% of the original price.

Calculating the Final Price

To calculate the final price of the jacket, we need to apply the discounts to the original price. Let's represent the original price of the jacket as $x$ . The first discount of $15 off can be represented as $x - 15$ . The second discount of 20% can be represented as $0.20x$ .

Applying the Discounts

To find the final price of the jacket, we need to apply the discounts to the original price. We can do this by subtracting the first discount from the original price, and then subtracting the second discount from the result.

Final\ price = (x - 15) - 0.20x

Simplifying the Expression

To simplify the expression, we can combine like terms.

Final\ price = x - 15 - 0.20x
Final\ price = 0.80x - 15

Conclusion

In conclusion, the final price of the jacket can be represented by the expression $0.80x - 15$ . This expression takes into account the $15 off discount and the 20% discount applied to all purchases. By understanding how discounts affect the original price, we can calculate the final price of the jacket.
