Answer:
$100 would be held as required reserves
$900 would be available to be given out as loans
Step-by-step explanation:
The required reserve is the minimum amount set by the Central bank that must be held as reserves by banks.
If $1000 is deposited and 10% is the required reserves, 0.1 × $1000 = $100 would be held as required reserves.
$1000 - $100 = $900 would be available to be given out as loans.
