Final answer:
Without the loan amount, we cannot accurately calculate Rich's monthly payment or total payback for the loan. The options provided do not contain enough information to solve the question.
Step-by-step explanation:
Rich's monthly payment and total payback for a 10-year loan at 5.9% require utilizing the formula for calculating the monthly payment of an installment loan. While the specific formula isn't provided in the question, generally it involves the loan amount, the interest rate, and the number of periods.
However, the options given (A, B, C, D) do not include enough information to accurately determine which is correct without knowing the loan amount.
If we had the loan amount, we could apply the formula and compare the results to the options. Due to a lack of information, we can't confidently choose between options A, B, C, and D.
