Economic- checkable deposits calculation rest - thank you?

Question

National Bank holds $109,000,000 in checkable deposits and $1,125,000 in excess reserves under a required reserve ratio of 12 percent. Suppose customers of the bank bring in $5,000,000 in currency to add to their checkable deposits. How much money can this bank now create at maximum?

$4,400,000

$3,275,000

$5,525,000

$13,460,000

Answer 1

c) $5,525,000

5'000'000*(1-12%) + 1'125'000= 5'000'000*0.88 + 1'125'000= 4'400'000 + 1'125'000= 5'525'000
