The annual revenues (in $1000 units) associated with several large apartment complexes are $0, $350, $290, $460, $150, and $320 for years 0, 1, 2, 3, 4, and 5, respectively. Determine (1) whether each cash flow series is conventional or nonconventional, (2) the maximum number of real-number roots, and (3) if there is one, positive real-number i* value. The cash flows for years 0, 1, 2, 3, 4, and 5, respectively, are:
(a) $?1500, $?90, $?40, $?85, $?60, and $?90 (b) $?1500, $?450, $?300, $?400, $?125, and $?400 (c) $1500, $?450, $?300, $?500, $?200, $?400 (d) $?1500, $?450, $?300, $?400, $?125, and $?310

Thomas completed a study of a $1 million 3-year-old DNA analysis and modeling system that DynaScope Enterprises wants to keep for 1 more year or dispose of now. His table (in $1000 units) details the analysis, including an anticipated $100,000 selling price (SP) at the end of next year, SL depreciation, taxes at the all inclusive rate of Te = 52%, and PW at the after-tax MARR of 5% per year. Thomas recommends retention since PW > 0. Critique the analysis to determine if he made the correct recommendation.
