If $2940 is invested at 3.2% compounded quarterly, how much is in the account after 8 years?
tino4ka555 [31]

Answer:

The future value is $3793.776

Step-by-step explanation:

Given

PV = 2940 --- present value

r = 3.2\% --- rate

t = 8 --- time

n = 4 --- quarterly

Required

Determine the future value

This is calculated using:

FV = PV(1 + \frac{r}{n})^{nt

So, we have:

FV =2940 * (1 + \frac{3.2\%}{4})^{4*8

FV =2940 * (1 + \frac{3.2}{400})^{32

FV =2940 * (1 + 0.008)^{32

FV =2940 * (1.008)^{32

FV =2940 * 1.2904

FV =3793.776
