Final answer:

The future value of the ordinary annuity with payments of $9,400, at an interest rate of 6% compounded semiannually for 5 years, is approximately $107,760.18, with $94,000 from contributions and $13,760.18 from interest.

Step-by-step explanation:

To find the future value of an ordinary annuity, we use the formula:

FV = R \times \left(\frac{\left(1 + \frac{i}{n}\right)^{nt} - 1}{\frac{i}{n}}\right)

Where:

  • R is the regular payment amount
  • i is the annual interest rate (in decimal)
  • n is the number of times interest is compounded per year
  • t is the number of years

In this scenario, we have:

  • R = $9,400
  • i = 6% or 0.06
  • n = 2 (since the interest is compounded semiannually)
  • t = 5 years

Let's plug these values into the formula:

FV = $9,400 \times \left(\frac{(1 + \frac{0.06}{2})^{2 \times 5} - 1}{\frac{0.06}{2}}\right)

Calculating the terms within the parentheses first, we get:

(1 + 0.03)^{10} - 1

FV = $9,400 \times \left(\frac{(1.03)^{10} - 1}{0.03}

Now we compute the future value (FV) and determine the contributions and interest.

The total contributions are simply the payment amount times the number of periods:

Total contributions = R \times nt

Total contributions = $9,400 \times (2 \times 5) = $94,000

To find the total interest, we subtract the total contributions from the future value:

Total interest = FV - Total contributions

Using a calculator:

(1.03)^{10} - 1 \approx 0.343916

FV \approx $9,400 \times \left(\frac{0.343916}{0.03}\right) \approx $9,400 \times 11.46387 \approx $107,760.18

Total interest = $107,760.18 - $94,000 = $13,760.18

Therefore, the future value of the annuity is approximately $107,760.18, with $94,000 from contributions and $13,760.18 from interest (rounded to the nearest cent).
