Answer: Bank can lend an additional $1100.

Explanation:

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.
