Final answer:
the correct answer is A) The bank's desired reserve ratio is 6% and its actual reserves are $21,000.
Step-by-step explanation:
The bank's desired reserve ratio can be determined using the formula:
Desired Reserve Ratio = Desired Reserves / Deposits
In this case, the desired reserves are $8,000 and the deposits can be calculated as follows:
Deposits = Actual Reserves / (1 - Desired Reserve Ratio)
The bank's excess reserves are $13,000, so the actual reserves are:
Actual Reserves = Excess Reserves + Desired Reserves
By substituting the given values into the formulas, we can determine the bank's desired reserve ratio and actual reserves:
Desired Reserve Ratio = $8,000 / ($21,000 - $8,000) = 6%
Actual Reserves = $13,000 + $8,000 = $21,000
