The problem involves a loan of $14,500 borrowed for 3 years at an interest rate of 2.8% per year compounded semiannually. Let's solve each part systematically.

### Key information:
- Principal $ P = 14,500 $
- Annual interest rate $ r = 2.8\% = 0.028 $
- Compounding frequency: Semiannually, so $ n = 2 $ times per year
- Loan period $ t = 3 $ years

---

### Part a: **Amount of the semiannual payment**

The formula to calculate the semiannual payment is derived from the formula for an amortized loan payment:

\[
A = \frac{P \cdot r/n}{1 - (1 + r/n)^{-nt}}
\]

Where:
- $ A $ is the semiannual payment
- $ P $ is the principal loan amount
- $ r $ is the annual interest rate
- $ n $ is the number of compounding periods per year (in this case, 2 for semiannual)
- $ t $ is the total loan period in years

Let me calculate this for you.

### Part b: **Amount of the first payment going towards the principal**

To find the portion of the first payment going towards the principal, we need to calculate the interest portion first. The interest for the first period is calculated as:

\[
\text{Interest} = P \times \frac{r}{n}
\]

Then, the amount going towards the principal is:

\[
\text{Principal payment} = A - \text{Interest}
\]

---

### Part c: **Total amount of interest paid**

To calculate the total interest paid, we first need to find the total amount paid over the entire loan period:

\[
\text{Total amount paid} = A \times (n \times t)
\]

Then subtract the original principal from this value to get the total interest:

\[
\text{Total interest} = \text{Total amount paid} - P
\]

I'll compute the exact values now.Here are the results for each part of the question:

### a. Amount of the semiannual payment:
The semiannual payment $ A $ is approximately **$2,536.46**.

### b. Amount of the first payment going towards the principal:
The amount going towards the principal in the first payment is approximately **$2,333.46**.

### c. Total amount of interest paid:
The total interest paid over the life of the loan is approximately **$718.73**.

Would you like any further details or explanations?

Here are some related questions you might consider:
1. How would the payment change if the interest rate was compounded monthly?
2. What if the loan period was extended to 5 years? How would that affect the payments and interest?
3. How much interest would be paid if the rate increased to 4%?
4. What portion of each payment goes to principal versus interest over time?
5. How does semiannual compounding differ from continuous compounding in this scenario?

**Tip:** The more frequently interest is compounded, the more you end up paying in total interest, even if the difference in the rate seems small.
