The equations of the model are:

C = 50 + 0.7VD                        T={0.2}Y

1 = 75                                     X = 50

G = 100                                   IM = {0A5)Y

a. Compute the AE function and plot it in a diagram. What is total autonomous expenditure?

b. What is the slope of the AE function?

c. Compute the equilibrium level of national income.

d. Suppose X rises from 50 to 100. How does this affect the level of national income?

e. What is the simple multiplier in this model?
