Answer: Bank can lend an additional $1100.
Explanation:
Given that,
Bank's initial excess reserves = $800
Reserve ratio = 20%
New deposits = $1,000
Required reserves = 20% of 1000 = $200
So, the banks have to keep $200 in reserves and can lend rest $800.
As given in the question that bank lends $500 to molly and has an excess reserves of $800, so the bank can lend an additional $1100.
