where
A=Final Value
P=Principal Amount
r=interest rate in decimal
n=number of compounding per year
t=total number of years

If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365;

Given:
P=$1000
r=4% = 0.04
n=1
t=9
