Sagot :

To calculate the total amount accrued when you deposit the money in an account that earns compound interest you have to use the following formula

[tex]A=P(1+\frac{r}{n})^{tn}[/tex]

A: amount accrued

P: principal amount

t: time, years

r: interest rate, expresed as a decimal value

n: number of coumpound periods

For this exericse

The principal amount is P=$1000

The time is t= 9 years

The interest rate is 9%/100=0.09

The compounding periods are 12/year (the interest is compounded monthly) so for the 9 year time period is 9*12=108

[tex]\begin{gathered} A=1000(1+\frac{0.09}{108})^{9\cdot108} \\ A=2247.15 \end{gathered}[/tex]
