The money multiplier is the amount of money that is generated from the reserves of a bank:
$100/0.10 - $100 = $900 billion
The money supply is
$100/0.10 = $1000 billion of $1 trillion
If the reserves is changed to 20%, the money multiplier and money supply will decrease

Answer:

a) multiplier 10

b) money supply 1,000B

c) if the FED raises to 20% the minimum reverse ratio:

  mutiplier 5

  money suply 500B

Explanation:

a) the multiplier is 1 over the required reserve ratio as it assumes banks will lend all the cash above this threshold

1/0.1 = 10

b) money supply: reserve times mutiplier:

100 x 100 = 1,000 billions

c) if required reserve ratio incerase to 20% then:

multiplier 1/0.2 = 5

and money supply 100 x 5 = 500 billions
