Vo1 = (560/4.3+1)*80.
Vo2 = -(560/33)*Vo1.
Vo3 = -(560/33)*Vo2 = 3.02.
Vo2 = -(560/33)*Vo1.
Vo3 = -(560/33)*Vo2 = 3.02.

Vo1=560/4.3*80=1.0V.
Vo2=560/33*Vo1=1.7V.
Vo3=Vo=560/33*Vo2=3.02V.
Vo2=560/33*Vo1=1.7V.
Vo3=Vo=560/33*Vo2=3.02V.

Isn't Vo1 = (560/4.3 + 1)80?

Vo = (1+Rf/R1)(-Rf/R2)(-Rf/R3).
= (1+560/4.3)(-560/33)(-560/33),
= 3.02V.
= (1+560/4.3)(-560/33)(-560/33),
= 3.02V.

How 80 came? Explain it clearly.

Vo =(Vi) (1+Rf/R1)(-Rf/R2)(-Rf/R3).
= (80x10^-6)(1+560/4.3)(-560/33)(-560/33),
= 3.02V.
= (80x10^-6)(1+560/4.3)(-560/33)(-560/33),
= 3.02V.
