How to Calculate List Price from Sale Price

What is the method to calculate the list price of an item from the sale price?

How can we determine the original price when an item is on sale?

Answer:

To calculate the list price of an item from the sale price, you need to work with the discount percentage and the sale price.

When a store offers a certain percentage of discount on an item, you can calculate the list price by considering the remaining percentage that represents the sale price. In this case, the sale price is the percentage of the list price that remains after the discount is applied.

For example, if a store is having a 90% off sale and the sale price of an item is $170, you can calculate the list price by dividing the sale price by the remaining percentage of the list price. In this case, the remaining percentage is 10% (100% - 90%).

To find the list price, you would divide the sale price by 10% (or 0.10). Using the given example, the list price would be $170 / 0.10 = $1,700. This is the original price of the item before the discount was applied.
