Answer:
The correct answer is "The percentage changes in the money supply is equal to the percentage changes in the price level" according to the equation of exchange
Explanation:
The Equation of Exchange deals with the relationship between money and price level, and also between money and real GDP.
The equation simply states: M x V = P x Y
Where M = the money supply
V = the velocity of money
P = the price level
Y = real GDP
Velocity is the number of times the average dollar is spent to buy final goods and services in a given year.
Velocity can be calculated by using V = (P x Y ) / M
The equation tells us that total spending (M x V) is equal to total sales revenue (P x Y).
Since (P x Y) is equal to the real GDP, then M x V = real GDP
Velocity (V) and Real GDP (Y) are effectively constant in the short run, therefore any changes in money supply (M), will cause a proportional change in the price level (P).
This equation demonstrated a direct relationship between price and money supply. If V and Y are constant, a certain percentage change in money supply will cause an equal amount of change in the price level.
