Hi, could you please help me solve questions d, e, and f? Thank you!

Question 2
Refer to the information provided in Figure 23.9 below to answer the question(s) that follow.
Aggregate expenditures
($ millions)
225
200
175
150
AE

300
100 200
Aggregate output ($ millions)
Figure 23.9
a) Refer to Figure 23.9. Write the equation for the aggregate expenditure function (AE). Show
your work.
b) Refer to Figure 23.9. What is the equilibrium level of output in this economy? State the
equilibrium condition used to determine this.
c) Explain the forces that maintain/drive the economy to this equilibrium by considering what
will happen at the following two levels of output, $300 million and $100 million. You will need
to discuss changes in investment through unplanned inventories and the response of output.
d) Refer to Figure 23.9. How will equilibrium aggregate expenditure and equilibrium aggregate
output change as a result of a decrease in investment by $20 million?
e) The interest rate is an exogenous factor that effects the level of investment in an economy. If
the interest rate decreased, explain what would happen to planned investment. How would you
change the AE line drawn in 23.9 to reflect this change? What would happen to equilibrium
output?
f) Explain what Keynes meant by the phrase "animal spirits." Would animal spirits change
the location of AE and equilibrium output in the graph above? If so, be specific in your
explanation of how each would change
