a. Plot the graph of the consumption function for the available data. (2011-2020)

b. calculate the marginal propensity to consume for the period taking each couple of years (2011-2010; 2010-2009; and so on). PMC = C / YD

c. Calculate the marginal propensity to save for the period taking each couple of years (2011-2010; 2010-2009; and so on). PMA = A / YD

d. calculate the multiplier for each of the previous periods. The formula to calculate the multiplier is M = 1 / (1 - PMC).
