Answer:
c. $360 increase in excess reserves and a $40 increase in required reserves
Explanation:
Required reserves is the amount of reserves that is required by the Central bank that banks should keep.
Required reserve = reserve ratio × deposit
= 0.1 × $400 = $40
Excess reserve is the amount of reserves kept in excess of the required reserves.
Excess reserve = Deposit - Required reserve = $400 - $40 = $360
