The diagram below shows desired aggregate expenditure for a hypothetical economy.Assume the following features of this economy: • marginal propensity to consume (mpc) = 0.80
• net tax rate (t) = 0.15
• no foreign trade
• fixed price level
• all expenditure and income figures are in billions of dollars.
FIGURE 22-3

A) AE = 1000 + (0.68) Y
B) AE = 1000 + (0.80) 
C) AE = 1000 + (0.80) Y + 0.15 YD
D) AE = 1975 + (0.68) Y
E) AE = 1975 + (0.65) Y
