A) decrease by $200.
B) increase by $200.
C) decrease by $300.
D) increase by $300.

The multiplier effect is calculated as 1/(1-slope of AE curve). Here, it is 1/(1-0.67) = 3.03. Therefore, a $100 increase in autonomous spending will increase equilibrium expenditure by approximately $300 (100 * 3).
