Answer:
After 14 years, the compounded value of the invested amount = $733,200.27
Explanation:
What the question is asking us to find is the future value of an amount that is invested over a period of 14 years, compounded at 15% semiannually.
The formula is:

where ;
FV = Future value
PV = present value (principal)
i = nominal interest
n = compounding frequency in a year
t = total number of years.
Note: for investments that are compounded annually, n = 1, because compounding is once in a year, for those compounded semiannually, n=2, because compounding is twice in a year, for compounding done quarterly, n = 4 because there are four quarters in a year and so on.
Putting, the values into the equation above;


= $733,200 (to the nearest dollar)
