Consider the two mutually exclusive projects in the table below. Salvage values represent the net proceeds (after tax) from disposal of the assets if they are sold at the are of each year. Both projects B1 and B2 will be available (or can be repeated) with the same costs and salvage values for an indefinite period. (a) Assuming an infinite planning horizon, which project is a better choice at MARR = 14%? Use 15 years as the common analysis period. The present worth for project B1 is $ - 54.2 thousand The present worth for project B2 is S - 44.6 thousand. Which project is a better choice? Choose the correct answer below. (b) With a 10-year planning horizon, which project is a better choice at MARR = 14%? The present worth for project B1 is S -46. thousand. The present worth for project B2 is S - 38 9 thousand. Which project is a better choice? Choose the correct answer below
