Suppose the full employment level of real output (Q) for a hypothetical economy is $500, the price level (P) initially is 100, and prices and wages are flexible both upward and downward. Refer to the accompanying short-run aggregate supply schedules. In the long run, an increase in the price level from 100 to 125 will
a. increase real output from $500 to $560.
b. decrease real output from $500 to $440.
c. change the aggregate supply schedule from (a) to (c) and result in an equilibrium level of real output of $560.
d. change the aggregate supply schedule from (a) to (b) and result in an equilibrium level of real output of $500.
