Answer:
C) $500
Step-by-step explanation:
First we must determine the money multiplier = 1 / reserve ratio:
- money multiplier = 1 / 20% = 5
The bank's checkable deposits originally increase by $100, and since it will be able to lend all the money it can, $80, its checkable deposits will also increase by $80 x 5 (money multiplier) = $400.
So the total increase in the bank's checkable deposits = $100 (original deposit) + $400 (money created through loans) = $500
