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 equals=15?%? Use 15 years as the common analysis period.

?(b) With a10?-yearplanning? horizon, which project is a better choice at MARR equals=15?%?
