Answer:
The total amount of deposits in the banking system increases by $1.000, and the money supply increases by $800.
Step-by-step explanation:
Multiplier =1/reserve ratio
=1/0.2
=5
increase in deposits of banking system =deposit *multiplier
=200*5
=$1000
The initial deposits are in money supply itself, so we deduct that.
increase in money supply =increase in deposits -initial deposits
=1000-200
=$800
