Bill's father read that each year a car's value declines by 10%. He also read that a new car's value declines by 10% as it is driven off the dealer's lot. Mainte- nance costs and the costs of "car problems" are only $100 per year during the 2-year warranty period. Then they jump to $600 per year, with an annual increase of $400 per year.

Bill's dad wants to keep his annual cost of car ownership low. The car he prefers cost $22,000 new, and he uses an interest rate of 10%. For this car, the new vehicle warranty is transferrable.

(c) If he buys the car after it is 4 years old, what is the minimum cost life? What is the minimum EUAC?

(d) If he buys the car after it is 6 years old, what is the minimum cost life? What is the minimum EUAC?
