1. Aggregate expenditures and income
The following table shows consumption (C), investment (1), government spending (G), and net exports (X-M) in a hypothetical economy for various
levels of real GDP (Y). Assume that the price level remains unchanged at all levels of income. All figures are in billions of dollars.
Compute aggregate expenditures for each income level and fill in the last column In the following table.

The equilibrium output at this price level is equal to $800 billion.
Suppose real GDP is currently $900 billion. Assuming the price level remains constant, this would mean that
