Final answer:
In the graph for determining the equilibrium price level, the rightward shift of the value of money is due to changes in aggregate demand (AD). When the AD curve shifts to the right, it indicates an increase in the overall spending in the economy, which leads to a higher demand for goods and services. As a result, both the output level and the price level increase.
Step-by-step explanation:
In the graph for determining the equilibrium price level, the rightward shift of the value of money (represented by the leftward shift of the price level) is due to changes in aggregate demand (AD).
When the AD curve shifts to the right, it indicates an increase in the overall spending in the economy, which leads to a higher demand for goods and services. As a result, both the output level and the price level increase.
