4. A civil engineer has been promoted to manage engineered public systems. One of the products is an emergency intercept pump for potable water. If the tested water quality varies by a preset percentage, the pump automatically switches to preselected options of treatments or water sources. Her estimate of the initial equipment cost is $110,000 and could vary +20%. The equipment has a 5-year life. The annual labor savings are $50,000 and could vary +20%. Help her analyze the viability of this project at MARR of 15%, over a 10-year planning horizon. There is a one-time facilities cost of $150,000 for the entire planning horizon
