If $6700 is invested at 4.6% interest compounded semiannually, how much will the investment be worth in 15

The correct equation to use is as follows:

where A is the amount after t years, P is the principal, r is the annual interest rate expressed as a decimal and n is the number of times the interest is compounded in a year.
Plugging in the given values we get:

After 15 years the investment will be worth $13,253.90

Iwould like to think so. what’s the question you need with?
