va rog frumos din toata inima

Answer 1

1)a+b+c+d=950
a=75;b=3×a=3×75⇒b=225;c=(a+b)÷3=(75+225)÷3=300÷3=100⇒c=100
d=950-(a+b+c)=950-(75+225+100)=950-400⇒d=550
2)1 zi→924÷4=231 kg
2 zi→924÷2=462 kg
3 zi→924-(231+462)=231 kg
cat s-a incasat in fiecare zi;
1 zi→231×2=462 lei
2 zi→462×2=924 lei
3 zi→231×2=462 lei
3)petunii mov→35x8=280
petunii roz→280÷2=140
petunii albe→280+140=420
petunii rosii→1000-(280+140+420)=1000-840=160
