Assume the economy in this graph is initially made up of consumption (C) and $50 of investment (Ig) spending.  Then if government spending (G) of $50, exports (X) of $50, and imports (M) of $50 were included in the economy, what would the new equilibrium GDP be?   

Now assume the economy is expanded to include investment spe…

Now assume the economy is expanded to include investment spending of $100.  Therefore, GDP = 0.9DI + 50 + 100 Using the multiplier you calculated above, what will the impact be to equilibrium GDP as a result of adding investment to the aggregate expenditures model?
