To calculate the reserve ratio, you can use the formula:
\[ \text{Reserve Ratio} = \frac{\text{Reserves}}{\text{Deposits}} \]
From the T-account provided:
- Reserves = $4,250
- Deposits = $50,000
Plugging in these values:
\[ \text{Reserve Ratio} = \frac{4,250}{50,000} \]
Calculating this gives:
\[ \text{Reserve Ratio} = 0.085 = 8.5% \]
So, the bank’s reserve ratio is:
a. 8.5 percent.
