Answer:
the required reserves will increase by 1,200 dollars
Explanation:
the required reserve ratio is 20%
for each dollar the bank receive in deposit it can loan up to 80% and must keep 20%
the multiplier will be: 1 / 0.2 = 5
each dollar of deposit will increase the money supply by 5
and each dollar withdraw will decrease money supply by 5
Therefore, for this deposit of 6,000 dollars the bank will kept:
$6,000 x 20% = $1,200

The compound interest formula is:

Where:
A is the amount you will have.
P is the money you are investing.
r: is the interest rate (in decimals)
n: number of times the interest is compounded per year
t: time (in years)
The first thing is converting the rate from percentage to decimal:

Since the interest is compounded every month and a year has 12 months n=12.
Now we can replace the values in our formula:

We can simplify the exponents to get:

Finally, we can use our calculator to get 288463.33
After 18 your balance in your bank account will be $288463.33
