Suppose AB 1, AE2 and AE3 are parallel. Calculate the value of Point A (E: B? Show your work. Assuming the economy's aggregate expenditure line is AE 1, calculate how much increase would be in aggregate equilibrium output if there is a $10 million increase in planned investment. Show your work. Now suppose the economy's aggregate expenditure line is AEz. Calculate how much increase would be in aggregate equilibrium output if there is a $10 million increase in planned investment. Show your work
