Paula's Auto Care is considering the purchase of a new two truck. The garage doesn't currently have a two truck, and the S 70,000 price tag for a new truck would represent a major expenditure. Paula Lohman, owner of the garage, has compiled the estimates shown below in trying to determine whether the two truck should be purchased. Paula's good friend. Walter Collins, stopped by. He is trying to convince Paula that the two truck will have other benefits that Paula hasn't even considered. First, he says, cars that need towing need to be fixed. Thus, when Paula tows them to her facility, her repair revenues will increase. Second, he notes that the two truck could have a plow mounted on it, thus saving Paula the cost of plowing her parking lot, (Walter will give her a used plow blade for free if Paula will plow Walter's driveway.) Third, he notes that the truck will generate goodwill; people who are rescued by Paula's two truck will feel grateful and might be more inclined to use her service station in the future or buy gas there. Fourth, the two truck will have "Paula's Auto Care" on its doors, hood and back tailgate- a form of free advertising wherever the tow truck goes. Walter estimates that, at a minimum, these benefits would be worth the following: a) Calculate the new present value, ignoring the additional benefits described by Walter b) Calculate the net present value, incorporating the additional benefits suggested by Walter. c) Suppose Walter has been overly optimistic in his assessment of the value of the additional benefits. At a minimum, what would the present value of net annual case flows need to be for the project to be accepted
