Катя купила 7 ластиков по 6 рублей и 8 тетрадок по 3 рубля. Сколько стоит вся покупка? Сколько сдачи получила Катя, если отдала в кассу 70 руб?

Ответы

Автор ответа: DiSkOgirL

1) 6 * 7 = 42 - стоимость ластиков

2) 3 * 8 = 24 - стоимость тетрадок

3) 42 + 24 = 66 - общяя сумма

4) 70 - 66 = 4 - сдача

Автор ответа: DiMaNdOsiNA

7 по 6 рублей будет 42, 8 по 3 рубля будет 24. итого 66 рублей. 70-66=4 рубля сдачи!
