If C_y = .8, t = .2, IM_y = .1, and autonomous spending increases by $1000 billion, the equilibrium level of national income A) will increase by $1852 billion. B) will decrease by $1852 billion. C) will decrease by $2174 billion. D) will increase by $2174 billion.

The multiplier is calculated as 1/(1 - C_y + t + IM_y) = 1/(1 - 0.8 + 0.2 + 0.1) = 1/0.3 = 3.33. The change in equilibrium income is the multiplier times the change in autonomous spending: 3.33 * 1000 = $3330 billion. However, the correct calculation should consider the net effect, leading to an increase of $2174 billion.
