Answer
The money supply will increase more if the 2,000 dollars is from the Fed purchasing bonds. (If the money from the cookie jar is added to the bank, the money was already in the economy as currency.)
The bond purchase will create 40,000 dollars in new money supply, and the cookie jar deposit will create 38,000 dollars in new money supply--a difference of 2,000 dollars.

$2000/.5 = 40000$
$40000-2000=38000$
