eEgg is considering the purchase of a new distributed network computer system to help handle its warehouse inventories. The system costs $41,000 to purchase and install and $25,000 to operate each year. The system is estimated to be useful for 4 years. Management expects the new system to reduce the cost of managing inventories by $46,000 per year. The firm’s cost of capital (discount rate) is 11%. Required: 1. What is the net present value (NPV) of the proposed investment...
