Answer:
$600 billion
Explanation:
Given that,
Currency held by the public = $100 billion
Reserves held by banks = $50 billion
Bank deposits = $500 billion
The money supply refers to the total money in the circulation.
Therefore, the total money supply is as follows:
= Currency held by the public + Deposits with the bank
= $100 billion + $500 billion
= $600 billion
