Ответ:

69

Пошаговое объяснение:

1)3*3*5=45(пучков)-сколько пучков покупала бабушка по будним дням(5 раз в неделю);

2)3*4*2=24(пучков)-по выходным(2 раза в неделю);

3)45+24=69(пучков)-всего, по выходным и будним вместе.

Ответ:69 пучков


anasttassia: либо можно посчитать за одну неделю и умножить на 3
то есть 5*3+2*4=23 - пучков за одну неделю
потом 23*3=69 - пучков за три недели
