a. The consumption function is C = C0 + cYd, where C0 is autonomous consumption, c is marginal propensity to consume, Yd is disposable income.

b. The equation of the AE curve is: AE = Y = C + I + G + NX.

c. The equilibrium expenditure is when AE = Y = C + I + G + NX.

d. Calculate the multiplier formula is: m = 1/(1 - c(1 - t)), where c is marginal propensity to consume, t is marginal tax rate.
