Answer: is; less than
Step-by-step explanation:
An economy is said to be in short-run equilibrium in a scenario whereby the aggregate amount of output that is demanded is equal to the aggregate amount of output that is supplied. In this situation, the quantity demanded of Real GDP and the quantity supplied of Real GDP in the short run both equal $9.7 trillion, therefore, the economy is in short run equilibrium.
Since the quantity supplied of Real GDP in the long run is $10.2 trillion which is higher than the $9.7 trillion supplied in the short run, then there'll be a reduction in the price level in the long run equilibrium as thus will be less than 210.
