Final answer:
The question deals with calculating a single equivalent payment based on three future payments using a present value approach at an interest rate of 8.99%, but the relevant reference information given does not solve the problem directly. An exact answer cannot be provided with the information available.
Step-by-step explanation:
The student's question involves calculating the single equivalent payment that replaces three scheduled payments, using the time value of money concept at an interest rate of 8.99%. The relevant information provided in the question does not directly solve the problem but touches on the principles of loan payments and the effect of making additional payments or adjusting the payment amounts. Present value calculations would be required to determine the equivalent single payment.
Unfortunately, the provided reference information about loan payments, interest rates, and present value calculations are not directly applicable to solving the exact problem that the student asked about, which involves calculating a single payment based on different future payments and different time frames. Therefore, an exact numerical answer cannot be provided based on the details given in the question.
