assumptions

• each product has to have its own line fitting this regex (case insensitive): "^(\d+) (.*) at ([-+]?\d+).(\d{2})$"
• the input price is meant for the quantity of 1
• multiple whitespaces should be ignored in the product name
• an imported product has the substring "imported" (case insensitive)
• if a product is imported it should be the first part in the receipt (after the quantity)
• round up to the nearest 0.05 means: round n up to the nearest 0.05, which is >= n
