Exercise 2

Unless stated otherwise, discrete compounding of interest and end-of-period cash flows should be assumed in all problem exercises for the remainder of the book. All MARRs are "per year." The number in parentheses that follows each problem refers to the section from which the problem is taken.
Buildings that are constructed to be environmentally responsible are referred to as "green buildings." They cut down on energy consumption, increase water efficiency, improve indoor air quality, and use recycled materials in their construction. According to recent studies, money spent on a green buildingwill pay for itself ten times over the 50-year life of the building. Assuming end-of-year annual savings of P /5, where P is the investment cost of the building, draw a cash flow diagram for this situation.
