Consider the following national income model :

Y = C + I + G_o

C = 215 + 0.59Y

4.5I = 197 + 0.22Y

Where G_o = 90

(b) What is the determinant of the coefficient matrix?

(Give your answer to 'three' decimal places, if possible)

(Note: you can use either inversion or Cramer's rule to find thevalues of Y, C and I.)

(c) What is the equilibrium value of Y?

(Give your answer to 'three' decimal places, if possible)

(d) What is the equilibrium value of C?

(Give your answer to 'three' decimal places, if possible)

(e) What is the equilibrium value of I?

(Give your answer to 'three' decimal places, if possible)
