Need help figuring out how to solve this question.

6. Chase has estimated that its average daily net transaction accounts balance over the recent 14-day reserve computation period was $300 million. The average daily balance with the Fed over the 14-day maintenance period was $8 million, and the average daily balance of vault cash over the two-week computation period was $8.5 million. a. Under the rules effective in 2015, what is the amount of average daily reserves required to be held during the reserve maintenance period for these net transaction accounts balances? b. What is the average daily balance of reserves held by the bank over the maintenance period? By what amount were the average reserves held higher or lower than the required reserves? c. If the bank had transferred $30 million of its deposits every Friday over the two-week computation period to one of its offshore facilities, what would be the revised average daily reserve requirement
