The original price is $199.94
Given:
Discounted price = 159.95
Discount rate = 20%
If the discount rate is 20%, then the price is equivalent to 80%.
To get the original price, simply divide the discount price by its corresponding percentage.
Original price = 159.95 ÷ 80% = 199.94
To check
199.94 * 20% = 39.99 * value of the discount
199.94 - 39.99 = 159.95 *discounted price
