A store in the city offers different discounts depending on a persons purchase. A software determines discounts based on the customers purchase price range, based on the following rules: A purchase in the price range of 1 up to and including 50 has no discount, a purchase in the price range of over 50 up to and including 200 has a 5% discount, purchases of price range 201 up to and including 500 have a 10% discount, and purchases of price range 501 up to and including 2500 have 15% discounts. No items are sold outside these price ranges and if an incorrect price is entered the software returns a discount value of -1% to indicate an error.
