We are considering the purchase of a $130,000 computer-based inventory management system. It will be depreciated straightline to zero over its four-year life. It will be worth $30,000 at the end of that time. The system will save us $60,000 before taxes in inventory-related costs. The relevant tax rate is 21%. Because the new setup is more efficient than our existing one, we will be able to carry less total inventory and thus free up $50,000 in net working capital (NWC). The CFFA in Yr0 is $ (input an integer) [Hint: CFFA 0 = purchase - free-up. Do NOT forget the "-" sign in your answer.] The CFFA in Yr1 is $ - (input an integer) [Hint: CFFA 1= Depr + EBIT Tax] The CFFA in Yr4 is $ (input an integer)
