Кажется, переменная не используется, только инициализируется

Лучше сначала округлить, а потом взять остаток от деления по модулю 100
Стоит добавить if с проверкой, что addsInvert >= 11 и <=19, тогда возвращать рублей

А здесь добавить деление по модулю 10, чтобы брать последнюю цифру
| persons = input.nextInt(); | ||
| if (persons <= 0) {System.out.println("Количество участников отрицательно или равно нулю. Попробуйте еще раз.");} | ||
| else if (persons == 1) {System.out.println("Нет необходимости делить счет");} | ||
| else if (persons >0) {break;} |

Можно здесь поставить просто else, потому что с предыдущими проверками тут members >0 будет всегда true
