(15 points) Rondo is in the market for a new car. He has narrowed his search down to 2 models. Model A costs $32,000 and Model B costs $28,000. With both cars he plans to pay cash and own them for 4 years before trading in for a new car. His research indicates that the trade in value for Model A after 4 years is 60% of the initial purchase price, while the trade in value for Model B is 45%. The interest rate is 5%. For simplicity assume that operating and maintenance costs for the models are identical. Which model is the better decision and how much "cheaper" is it than the alternative?
