Your firm is contemplating the purchase of a new $$520,000$ computer$-$based order entry system. The system will be depreciated straight$-$line to zero over its five$-$year life. It will be worth $$56,000$ at the end of that time. You will be able to reduce working capital by $$81,000$ at the beginning of the project. Working capital will revert back to normal at the end of the project. The tax rate is $22$ percent and the required return on the project is $10$ percent.
