Therefore the Monetary base is $90 billion

b . Calculation to determine The quantity of money

Using this formula

Quantity of money =Deposits+Bank notes​ (dollar bills)

Quantity of money=$300 billion+$30 billion

Quantity of money=$330 billion

Therefore Quantity of money is $330 billion

Currency drain ratio=10 percent

Therefore Currency drain ratio is 10 percent sure
