1(a) Given the national income model Y = C + I + G where C = 100 + 0.75Y, I = 120 - 20i, G= 80, derive an expression for equilibrium in the goods market in the form i = f(Y).
(b) Given the money demand function, MD = 600 + 0.4Y - 40i, and supply function, MS = 900, derive an expression for equilibrium in the money market in the form i = f(Y).
(c) Graph both equations on the same diagram, showing the intercepts and slope.
