1. Consider an economy with no international trade and no taxes, whose macroeconomic conditions are are given by the following equations: C= 100,000 + 921' I = 40,000 G = 25,000 C is consumption spending, I is investment spending, and G is government spending on goods & services. a. What is the equilibrium level of aggregate output for this economy? b. What is the saving function for this economy? c. Check the solution, as we did in class, by showing that at the equilibrium level of Y total spending exactly matches the level of output. At the equilibrium level of Y, what is the level of saving in the economy? d. Sketch the solution in a graph using PowerPoint. PowerPoint's drawing program enables you to construct good-looking diagrams, and it's is a good skill to have. Go here for a basic tutorial: https:f/www.youtube.com/watch?v=M5X zvh2j9Y. After constructing the diagram in PowerPoint you can cut & paste it into a Microsoft Word document. e. What is the Keynesian multiplier for this economy? If I increases by $4,000, what will be the new equilibrium level of Y
