Answer: shows the amount of real GDP that will be demanded at each possible price level.
Step-by-step explanation:
The Aggregate Demand curve shows how much of real GDP is demanded at each possible price level which means that is shows the effect of the price level on real GDP.
If the price level rises, real GDP will decrease and if the price level falls, real GDP rises. This is why the aggregate demand curve is downward sloping, to reflect this inverse relationship between real GDP and price level.
