1. e. The Fed buys a security from a bank for $1,000.
In order to increase money supply, the Fed buys a security from the bank and gives them money.
2. d. The bank sets $100 aside as required reserves.
The bank will set aside 10% of the money paid by the Fed which comes to $100 leaving the bank with $900.
3. a. The bank lends $900 to a customer needing a loan.
The bank then lends this money to customer who needed it.
4. c. The customer spends the $900 at a store.
The customer then spends the money thereby transferring it to another party.
