Examine the Table 1 information provided and perform the following activities for Table 2:

1. For each level of Real GDP, calculate aggregate expenditure, unplanned change in inventories, and indicate what will happen to GDP (increase, decrease or be in equilibrium). Explain how you derived the Aggregate Expenditure and Unplanned Change in Inventories values.
2. Explain how the values in the Unplanned Change in Inventories column dictate what will happen to the Real GDP.
