Discounted price = 24

discount rate = 20%

When an object is sold at a discount.

You can simply multiply the original price by the discount rate to get the value of the discount.

Original Price * Discount Rate = Value of the discount

Then, you subtract the value of the discount from the Original price to get the discount price

Original Price - Value of the discount = discounted price

Remember: The discount price can also be arrived at by multiplying the Original price with the difference of 100% and the discount rate, in its decimal form.

Original price * (100%-discount rate) / 100 = Discount Price

Using the latest formula, we can compute for the original price by dividing the discount price by the difference of 100% and the discount rate, in its decimal form.

Original Price = Discount Price / (100%-discount rate) / 100

Original Price = 24 / (100%-20%) / 100

= 24 / 0.80

Original Price = 30

Discount Value = 30 * 20%/100%

= 30 * 0.20

Discount Value = 6

Discount Price = 30 - 6

Discount Price = 24
