The amount of money which the bank need to hand all times is $7 million
Step-by-step explanation:
The amount of money which the bank need to hand all times is computed as:
First computing the amount of reserve as:
Reserve amount = Deposit amount × Reserve requirement percent
where
Deposit amount is $10 million
Reserve requirement percent is 30%
Putting the values above:
Reserve amount = $10 million × 30%
Reserve amount = $3 million
Now, computing the amount of money which bank need to hand:
Amount of money = Deposit amount - Reserve amount
Amount of money = $10 million - $3 million
Amount of money = $7 million
