Answer:
If the required reserve ratio is 0, that means that the money multiplier will be infinite. I guess the question is incomplete.
I looked for similar questions to fill in the blanks:
If you deposit $2,400 and the required reserve ratio is 0.4, then by how much does the money supply increase?
first we must determine the money multiplier = 1 / required reserve ratio = 1 / 0.4 = 2.5
to determine the total effect on the money supply we just multiply the deposit by the multiplier = $2,400 x 2.5 = $6,000 increase.
