Answer:
A. $1000
Step-by-step explanation:
First Bank's Excess Reserves = $5,000
Amount of Check = $6,000
First Bank's amount short of reserve = Excess Reserves - Amount of deposit withdraw
First Bank's amount short of reserve = $5,000 - $6,000
First Bank's amount short of reserve = -$1,000
First Bank is short of reserves in the amount of $1,000.
