Question 1193768
**a. Determine the Number of Semi-Annual Payments**

* **Find the effective semi-annual interest rate:** 
    * Semi-annual interest rate = (1 + Annual Interest Rate / Number of compounding periods per year)^(Number of compounding periods per year) - 1
    * Semi-annual interest rate = (1 + 0.10 / 2)^(2) - 1 
    * Semi-annual interest rate = 0.0525 or 5.25%

* **Use a financial calculator or spreadsheet software (like Excel or Google Sheets) to determine the number of payments.**

    * **In Excel, you can use the NPER function:** 
        * `=NPER(rate, pmt, pv, [fv], [type])`
            * rate: Semi-annual interest rate (0.0525)
            * pmt: Payment amount (-2000) 
            * pv: Present value (38000)
            * fv: Future value (0, as the loan will be fully paid off) 
            * type: 0 for payments at the end of each period (default)

    * This will give you the number of semi-annual payments required to repay the loan.

**b. Calculate the Smaller Final Payment**

1. **Calculate the remaining balance after the last full payment of P2,000:**
   * This involves calculating the remaining balance after the number of full payments determined in part (a). You can use the financial calculator or spreadsheet functions like `FV` (future value) to calculate the remaining balance after these payments.

2. **Calculate the interest accrued on the remaining balance:**
   * Multiply the remaining balance by the semi-annual interest rate.

3. **Calculate the final payment:**
   * Final payment = Remaining balance + Interest accrued on the remaining balance

**Note:**

* This approach provides a general framework for solving this type of loan repayment problem. 
* The specific calculations will require the use of financial tools or software.
