Consider the imaginary small country of Auyuittuq. Assume that Auyuittuq is closed to trade, so that its net exports are equa the economy is described by the following consumption function, where C is consumption, Y is income (real GDP), Ip is planned investment, G is government purchases, and T is taxes: C = $40 billion +0.5 x (Y-T) Suppose G = $115 billion, Ip = $50 billion, and T = $10 billion. Given the consumption function and the fact that, in a closed economy, planned expenditure can be calculated as Y=C+Ip+ G, the equilibrium income level is $ billion.

Consider the imaginary small country of Auyuittuq. Assume that Auyuittuq is closed to trade, so that its net exports are equal to zero. Suppose that
the economy is described by the following consumption function, where Cis consumption, Y is income (real GDP), Ip is planned investment, G is
government purchases, and T is taxes:
C = $40 billion +0.5 x (Y-T)
Suppose G= $115 billion, Ip = $50 billion, and T $10 billion.
Given the consumption function and the fact that, in a closed economy, planned expenditure can be calculated as Y=C+Ip+ G, the equilibrium
income level is
billion.
Suppose that government purchases are increased by $100 billion. The new equilibrium level of income will be equal to S
billion.
Based on the effect of the change in government purchases on equilibrium income, you can tell that this economy's multiplier is equal to
