Answer to Question 1

The simple deposit multiplier is equal to (1/required reserve ratio). In this case it is 1/0.1 = 10. Since the deposit multiplier is 10, then a decrease in deposits in the banking system is equal to the multiplier times the initial withdrawal. The change in deposits will be negative as the withdrawal will shrink deposits in the banking system. This is 10  -25,000 = -250,000. To find the change in the money supply, we must then add back the initial withdrawal, as now cash held by the public increases by the size of the initial withdrawal. Thus the change in the money supply is -250,000 + 25,000 = -225,000.
