Find the accumulated value of an investment of $7000 at 12% compounded semiannually for 12 years.

Mashcka [7]

Answer:

$28,342.54

Step-by-step explanation:

The value of an account earning compound interest is found using the formula ...

A = P(1 +r/n)^(nt)

where P is the principal invested at annual rate r compounded n times per year for t years.

You have P=7000, r=0.12, n=2, t=12.

Using these values in the formula, we find the accumulated value of the investment to be ...

A = 7000(1 +0.12/2)^(2·12) = 7000(1.06^24) ≈ 28,342.54

The value after 12 years is $28,342.54.
