Understanding the Problem

When it comes to discounts, it's not uncommon to see prices reduced by a certain percentage. However, calculating the original price of an item after a discount can be a bit tricky. In this article, we'll explore how to find the original price of a glove that is $28 after a 30% discount.

The Formula for Finding the Original Price

To find the original price of an item after a discount, we can use the following formula:

Original Price = Discounted Price / (1 - Discount Percentage)

In this case, the discounted price is $28, and the discount percentage is 30%. Plugging these values into the formula, we get:

Original Price = $28 / (1 - 0.30)

Simplifying the Equation

To simplify the equation, we can start by calculating the value of (1 - 0.30). This is equal to:

1 - 0.30 = 0.70

Now, we can plug this value back into the equation:

Original Price = $28 / 0.70

Calculating the Original Price

To calculate the original price, we can divide $28 by 0.70:

Original Price = $40

Conclusion

In this article, we've seen how to find the original price of a glove that is $28 after a 30% discount. By using the formula for finding the original price, we were able to calculate the original price as $40. This demonstrates the importance of understanding how to calculate discounts and original prices in everyday life.

Q: What is the formula for finding the original price of an item after a discount?

A: The formula for finding the original price of an item after a discount is:

Original Price = Discounted Price / (1 - Discount Percentage)

Q: How do I calculate the original price of a glove that is $28 after a 30% discount?

A: To calculate the original price of a glove that is $28 after a 30% discount, you can use the formula:

Original Price = $28 / (1 - 0.30) Original Price = $28 / 0.70 Original Price = $40

Q: What if the discount is not a percentage, but a fixed amount? How do I calculate the original price?

A: If the discount is not a percentage, but a fixed amount, you can calculate the original price by subtracting the discount from the discounted price, and then dividing by (1 - discount percentage). For example, if the discounted price is $28, and the discount is $5, and the discount percentage is 30%, you can calculate the original price as follows:

Original Price = ($28 + $5) / (1 - 0.30) Original Price = $33 / 0.70 Original Price = $47

Q: How do I calculate the original price of an item if the discount is a buy-one-get-one-free offer?

A: If the discount is a buy-one-get-one-free offer, you can calculate the original price of the item by dividing the price of one item by 2. For example, if the price of one item is $20, the original price of the item would be:

Original Price = $20 / 2 Original Price = $10

Q: What if the discount is a percentage off the original price, rather than the discounted price? How do I calculate the original price?

A: If the discount is a percentage off the original price, rather than the discounted price, you can calculate the original price by dividing the discounted price by (1 - discount percentage). For example, if the discounted price is $28, and the discount is 30% off the original price, you can calculate the original price as follows:

Original Price = $28 / (1 - 0.30) Original Price = $28 / 0.70 Original Price = $40

Q: How do I calculate the original price of an item if the discount is a combination of a percentage and a fixed amount?

A: If the discount is a combination of a percentage and a fixed amount, you can calculate the original price by first calculating the discount amount, and then subtracting that amount from the discounted price. For example, if the discounted price is $28, and the discount is 30% off the original price, and the discount amount is $5, you can calculate the original price as follows:

Discount Amount = $28 x 0.30 Discount Amount = $8.40 Discount Amount = $5 Total Discount Amount = $8.40 + $5 Total Discount Amount = $13.40 Original Price = $28 + $13.40 Original Price = $41.40

Q: What if the discount is a price match guarantee? How do I calculate the original price?

A: If the discount is a price match guarantee, you can calculate the original price by finding the lowest price of the item at a competitor's store, and then using that price as the original price. For example, if the price of the item at a competitor's store is $40, and the price of the item at your store is $28, you can calculate the original price as follows:

Original Price = $40
