To determine the velocity of money, you can use the formula:
\[ V = \frac{PY}{M} \]
where:
- \( V \) is the velocity of money,
- \( P \) is the price level,
- \( Y \) is the real output (GDP),
- \( M \) is the money supply.
Given the values:
- \( M = 3,000 \)
- \( P = 2 \)
- \( Y = 6,000 \)
Now plug in the values into the formula:
\[ V = \frac{(2)(6,000)}{3,000} \]
Calculating the numerator:
\[ 2 \times 6,000 = 12,000 \]
Now plug this into the equation:
\[ V = \frac{12,000}{3,000} \]
Now dividing:
\[ V = 4 \]
So, the velocity of money is:
