Question

The table below shows some of the expenditure amounts in the economy of Arkinia. The MPC, the MTR, and the MPM are all constant, as are the values of the three injections.

a. Complete the table below.

Y	T	YD	C	S	I	G	X	IM	XN	AE
0					50	180	50
100		60		-5	50	180	50		30
200	60		130	10	50	180	50
300	80		195		50	180	50	40
400	100			40	50	180	50	50
500			325		50	180	50	60
600		460			50	180	50
700			455		50	180	50
800		620		100	50	180	50		-40

  

Draw a 45° line (labelled Y) and the aggregate expenditure function, labelled AE₁. Identify expenditure equilibrium with the letter e₁. Use the tool "e1" to show the expenditure equilibrium. Plot only the endpoints of Y and AE. Once all points have been plotted, click on the line (not individual points) and a tool icon will pop up. You can use this to enter exact co- ordinates for your points as needed.

  

b. The value of equilibrium income is $ 600

c. At equilibrium, the value of total injections is $ _____ and of total leakages is $ ______

d. The value of the MPE in Arkinia is ____ . Round your answer to 2 decimal places.

e. The value of the multiplier in Arkinia is ____ . Round your answer to 2 decimal places.

f. Suppose that exports from Arkinia were to increase by $90. Draw the new aggregate expenditure function on the graph above, and label it AE₂. Remember to plot only the endpoints of AE_2.

g. The value of the new equilibrium income is $ 800 , and at equilibrium, the value of net exports is $ 50

I need help with the graph and question c,d,e. Thank You
