Answer: 4) No change in the money supply because the $200 in currency has been converted to a $200 increase in checkable deposits
Step-by-step explanation:
The money supply refers to the total amount of money currently in circulation. In this instance it remains the same because no new money was introduced into the economy.
All that has happened is that Ms. Rogers took her $200 which was already in circulation and part of money supply and deposited it in her checking account. The money is therefore still in circulation, just not in immediate cash.
Money supply therefore remains the same.
