Consider the hypothetical country of Nahanni. Suppose that national income in Nahanni is $30 billion, households pay $12 billion in taxes, household consumption is equal to $16 billion, and the marginal propensity to consume (MPC) is 0.7. On the following graph, use the blue line (circle symbol) to plot the economy's consumption function. CONSUMPTION (Billions of dollars) 50 45 40 35 30 25 20 15 10 5 - 0 0 5 10 15 20 25 30 35 40 45 50 DISPOSABLE INCOME (Billions of dollars) Consumption Function (?) Suppose now that Nahanni's national income increases to $35 billion. Assuming the amount paid in taxes is fixed at $12 billion and that MPC = 0.7, what is the new amount of household consumption? $19.5 billion $22.3 billion $21.6 billion $23.7 billion
