5.19 The Moo-Cow Dairy may purchase new milking equipment for its milking barn. The equipment costs
$135,000. The annual savings due to increased pro- duction and decreased labor costs will be $25,000. The equipment requires a minor overhaul every 2 years that costs $5000. At the end of the sixth year, a major overhaul costing $15,000 will be required. The equipment is expected to last 10 years with scheduled overhauls. No salvage value is antici- pated. If money is worth 7% to the dairy, determine the equipment’s PW. (Answer: $19.56K)
5.20 National Motors must build a bridge to access land for its manufacturing plant expansion. If made of normal steel, the bridge would initially cost $30,000, and it should last 15 years. Maintenance (cleaning and painting) will cost $1000 per year. If a more cor- rosion-resistant steel were used, the annual mainte- nance cost would be only $100 per year (with the same life). If the firm’s cost of money is 12%, what is the maximum amount that should be spent on the corrosion-resistant bridge?
