8.2 A new power plant will cost Newburg $2.1M to build and $230K per year to operate for its 25-year life, when its salvage value is zero. The higher efficiency of the new plant will lower utility bills by $21 per year for each of the 20,000 residents of Newburg. The plant’s air pollution will cost residents $3 each per year. If i = 5%, should the new power plant be built?
8.3 A new water treatment plant proposed for Anytown, USA, has an initial cost of $6M. The new plant will service the 7500 residential customers for the next
30 years. It is expected to save each customer
$125 per year. The plant will require a major over- haul every 5 years, costing $1M. Determine the ben- efit/cost ratio at the city’s interest rate of 6%.
