III. (30 points) Given the following information for a closed economy; C =$785 + 0.76Ya I = $890 G =$990 T = $836 1. Find the equilibrium level of aggregate income (Y) for this economy. Be sure to show the steps of your work and give a specific numerical answer. 2. What is the value of aggregate saving (S) for this economy at the equilibrium level of income? Give a specific numerical answer and show how you have found it. 3. Suppose the government raises the taxes (T) to $1,070 and at the same time it also increases its expenditures (G) to $1,400 from the levels shown above. By applying the tax multiplier (kr) and government expenditure multiplier (ko) principles, find the net change in the equilibrium level of income (Y) caused by these two measures. Also state the new equilibrium level of income (Y) following these measures. Be sure to clearly show the steps of your work and give specific numerical answers. 4. In a well-labeled diagram, demonstrate the results you have obtained in part 3 above. Be sure to indicate clearly the underlying changes in G and T, and the resulting changes in income (Y) that have taken place in part 3. Also, be sure to properly label the axes and all parts of your diagram
