Problem:

Your firm is contemplating the purchase of a new $669,000 computer-based order entry system. The system will be depreciated straight-line to zero over its six-year life. It will be worth $54,000 at the end of that time. You will save $174,000 before taxes per year in order processing costs, and you will be able to reduce working capital by $49,000 at the beginning of the project. Working capital will revert back to normal at the end of the project.

Requirement:

Question: If the tax rate is 40 percent, what is the IRR for this project?
