You can put this solution on YOUR website! **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.

You can put this solution on YOUR website! . A P38,000 loan bears interest at 10% compounded semi-annually and is to be repaid
 in semi-annual payments of P2,000 each.
 a. How many semi-annual payments must be the debtor make?
 b. What smaller final payment should he make six months after the last payment
 of P2,000 is made?
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 
 
Use the standard formula for the semi-annual payment for a loan
    P =  ,
where L is the loan amount; r =  is the effective semi-annual compounding interest rate;
n is the number of payments; P is the semi-annual payment.
In this problem  P = $2000;  r =  = 0.05.
Substitute these values into the formula and get for semi-annual payment
    2000 =  .
In this equation, n is the unknown: we should find n from this equation.
Simplify step by step  =  ,
    0.052631579 =  ,  =  ,
    1.05263158 =  ,  =  ,
    0.95 =  ,  = 1 - 0.95,  = 0.05,  = 0.05,
    1.05^n = 1/0.05,
    1.05^n = 20,
    n*log(1.05) = log(20),
    n =  = 61.4.
So, 61 full semi-annual payments should be made of 2,000 each,
and then the last,62-th payment, should be made of the lesser amount.
ANSWER.  61 full semi-annual payments should be made of 2,000 each,
         and then the last, 62-th payment, should be made of the lesser amount.
         The total number of semi-annual payments is 62.Solved.
