To find the original price when you know the discounted price and the discount percentage, you can use the following formula:
Original Price = Discounted Price / (1 – (Discount Percentage / 100))
In this case, the discounted price is 30 and the discount is 25%. Plugging these values into the formula:
Original Price = 30 / (1 – (25 / 100))
Original Price = 30 / (1 – 0.25)
Original Price = 30 / 0.75
Original Price = 40
So, the original price was 40.
