Нам нужно найти, сколько же кг любого варенья содержится в каждой банке. Для этого мы находим разность между количеством банок малинового и вишнёвого варенья:
20 б. – 16 б. = 4 банки.
Значит, если малинового варенья продано на 8 кг больше вишнёвого, то можно определить и сколько килограммов в одной банке:
8 кг : 4 б. = 2 кг
Теперь можно узнать, сколько килограммов вишнёвого варенья продано за день:
2 кг х 16 б. = 32 кг,
И сколько килограммов малинового варенья продано за день:
2 кг х 20 б. = 40 кг.
