У продавця солодощів було 10 кг цукерок за ціною 60 грн за кілограм і 15 кг цукерок — по 40 грн за кілограм. Мішки із цукерками розірвались, і всі цукерки перемішалися. Визнач ціну, за якою він продаватиме отриману суміш. Даю лучшую оценку и 100 балов!!!

Спочатку потрібно знайти загальну вагу цукерок:
10 кг + 15 кг = 25 кг
Далі потрібно знайти загальну вартість цукерок:
10 кг * 60 грн/кг = 600 грн
15 кг * 40 грн/кг = 600 грн
Загальна вартість цукерок: 600 грн + 600 грн = 1200 грн
Отже, середня ціна за кілограм цукерок:
1200 грн / 25 кг = 48 грн/кг
Це означає, що продавець повинен продавати отриману суміш за ціною 48 грн за кілограм.
