Final answer:

To calculate the number of payments needed to pay off the loan, use the loan formula. In this case, approximately C) 63 payments are needed to pay off the loan.

Step-by-step explanation:

To calculate the number of payments needed to pay off the loan, we can use the loan formula:

Loan = Payment*((1+r)^n - 1)/(r*(1+r)^n)

Where Loan is the initial loan amount, Payment is the monthly payment, r is the monthly interest rate, and n is the number of payments.

In this case, Loan = R500 000, Payment = R6000, and r = 9%/12 = 0.0075.

Substituting these values into the formula, we get:

R500 000 = R6000*((1+0.0075)^n - 1)/(0.0075*(1+0.0075)^n)

Multiplying both sides by 0.0075*(1+0.0075)^n, we get:

3750*(1.0075^n - 1) = (1+0.0075)^n

Now, we can solve this equation for n using either trial and error or a calculator. In this case, the number of payments needed is approximately 63 payments.
