Answer:

75 banci si 150 scaune

Explanation:

Ce stim:

1 clasa → 15 banci si 30 scaune

Ce aflam in modul 1:

5 clase → (15+15+15+15+15) banci si (30+30+30+30+30) scaune

Raspuns:

5 clase → 75 banci si 150 scaune

Ce aflam in modul 2:

5 clase → 15·5 = 75 banci si 30·5 = 150 scaune

Raspuns:

5 clase → 75 banci si 150 scaune
