XBC Inc. is planning to buy a new car. Model A costs $22,000 and is expected to have a life of 4 years. Model B costs $35,000 but it is expected to last 6 years. Model B provides a better warranty and it will save the company an average of $1,000 per year in covered costs. At the end of its life, either car can be replaced with a similar model at the same cost. The salvage value is expected to be 10% of original cost for either model. Using annual worth analysis and an interest rate of 5% per year, determine the better buy.
