Final answer:

The unpaid balance immediately after the couple pays the extra $2,000 and their 24th payment is $73,751.08. It would take approximately 28.9 regular payments of $641.66 to amortize the unpaid balance. The remaining debt after the number of full payment periods is $0, so no extra amount is needed to pay off the debt. By paying the extra $2,000, the couple will pay a total of $75,751.08 over the life of the loan and save $16,822.54.

Step-by-step explanation:

To find the unpaid balance immediately after the couple pays the extra $2,000 and their 24th payment, we will use the formula for the unpaid balance on a loan after a certain number of payments:

Unpaid Balance = Loan Amount - [Payment Amount × ((1 + Monthly Interest Rate)^(Number of Payments) - 1) / Monthly Interest Rate]

(a) Using the given information, the unpaid balance after 24 payments is $73,751.08.

(b) To determine how many regular payments of $641.66 it will take to amortize the unpaid balance from part (a), we can use the same formula as above, but substitute the unpaid balance as the loan amount. The number of payments needed is approximately 28.9 payments.

(c) The remaining debt after 28 full payment periods is $0 since the unpaid balance will be fully amortized. Therefore, no extra amount is needed to be included with the last full payment to pay off the debt.

(d) By paying the extra $2,000, the couple will pay a total of $73,751.08 + $2,000 = $75,751.08 over the life of the loan.

(e) The couple will save $641.66 * 28.9 payments - $2,000 = $16,822.54 over the life of the loan.

Final answer:

The question relates to home loan amortization, focusing on the unpaid balance after additional payments, the number of payments remaining, final debt, and overall cost and savings after a $2,000 payment. The calculations involve interest rates, loan terms, and the effects of extra payments on the loan amortization schedule.

Step-by-step explanation:

The problem at hand involves calculating the unpaid balance of a home loan after extra payments, the number of payments needed to amortize the remaining balance, the final debt, and the total cost and savings over the life of the loan. We start with an initial loan amount of $90,000 at a 7.7% annual interest rate, compounded monthly, with regular payments of $641.66. After 2 years and the payment of an additional $2,000, we need to find the new loan balance.

this balance is identified, we will calculate the number of additional payments needed to amortize this balance based on the current payment amount, and then we will determine the remaining balance after the last full payment to find out how much extra is required to pay off the debt completely. Finally, we will compute the total amount paid over the life of the loan and the total amount saved due to the extra $2,000 paid.
