Answer 2

Solution for Calculating the Original Price of the Item

To calculate the original price of the item before the discount, we can use the following formula:

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

Given that the item was discounted by 20% and now costs 680 rubles, we can use the formula to find the original price.

Original Price = 680 / (1 - 0.20)

Original Price = 680 / 0.80

Original Price = 850 rubles

Therefore, the original price of the item before the discount was 850 rubles.
