Final answer:
To find the present value (P) amount that will grow to $280,000 if it is invested at 6% compounded semiannually for 13 years, use the formula for compound interest.
Step-by-step explanation:
To find the present value (P) amount that will grow to $280,000 if it is invested at 6% compounded semiannually for 13 years, we can use the formula for compound interest:
P = F / (1 + r/n)^(n*t)
Where P is the present value, F is the future value, r is the interest rate, n is the number of compounding periods per year, and t is the number of years.
Plugging in the given values:
P = 280,000 / (1 + 0.06/2)^(2*13)
P ≈ $118,916.46
