Only short explanations are needed. I really appreciate your help.

We assume the following for the simple macro model: The autonomous consumption is 100 and the marginal propensity to consume is 0.7. The net tax rate is 10%. Government Purchase is given by 200. The export is 150 and the marginal propensity to import is 7% 1. Write down the AE function. Draw the AE function in the graph. 2. Compute the equilibrium real national income. Show the equilibrium in the graph. 3. Define the simple multiplier. Compute the simple multiplier. 4. What is the government budget balance at the equilibrium level of GDP? 5. What is the value of the net exports at the equilibrium level of GDP? 6. Compute the national saving in the equilibrium
