Пользователь может ввести на вопрос про количество человек вместо целого числа строку, и приложение упадет. Для стоимости товаров ты обрабатываешь такую ситуацию, стоит добавить обработку и для количества людей, чтобы приложение не падало/ Можешь использовать try-catch или hasNextInt

Все поля и методы класса лучше делать не статическими (убрать static у всех), в этом нет необходимости. А при вызове метода в Main создавать объект класса:
Calculator calc = new Calculator();
calc.printResult(numberOfGuests);
