To calculate the money multiplier, we can use the formula:
\[ \text{Money Multiplier} = \frac{1}{\text{Reserve Ratio}} \]
First, we need to find the reserve ratio. The reserve ratio is defined as the ratio of reserves to total deposits.
From the T-account given in Table 29-3:
- Reserves = $4,250
- Deposits = $50,000
Now we can calculate the reserve ratio:
\[ \text{Reserve Ratio} = \frac{\text{Reserves}}{\text{Deposits}} = \frac{4,250}{50,000} = 0.085 \]
Now, we can use the reserve ratio to calculate the money multiplier:
\[ \text{Money Multiplier} = \frac{1}{\text{Reserve Ratio}} = \frac{1}{0.085} \approx 11.76 \]
Therefore, the value of the economy's money multiplier is approximately 11.76.
The correct answer is a. 11.76.
