Здравей,

малко дребни грешки са преобърнали нещата. Може да ги разгледаш в коригирания ти код

        double priceForBrandies = whiskeyPriceInBGN / 2;
        double priceOfWine = priceForBrandies - (0.4 * priceForBrandies);
        double priceOfBeer = priceForBrandies - (0.8 * priceForBrandies);
        double amountForBrandies = litersOfBrandies * priceForBrandies;
        double amountOfWine = litersOfWine * priceOfWine;
        double amountForBeer = litersOfBeer * priceOfBeer;
        double amountForWhiskey = litersOfWhiskey * whiskeyPriceInBGN;

Поздрави :)
