In order to provide drinking water as part of its 50-year plan, a west coast city is considering constructing a pipeline for importing water from a nearby community that has a plentiful supply of brackish ground water. a full-sized pipeline can be constructed at a cost of $122 million now. alternatively, a smaller pipeline can be constructed now for $80 million and enlarged 20 years from now for another $100 million. the pumping cost will be $25,000 per year higher for the smaller pipeline during the first 20 years but will be approximately the same thereafter. both pipelines are expected to have the same useful life with no salvage value. ( a ) at an interest rate of 6% per year, which alternatively is more economical? ( b ) write the spreadsheet function to display the pw for the smaller pipeline alternative.

anyone below or above ambitious can tell you. so crowns mean brainliest. getting brainliest means your answer needs a good explanation and the person asking the question can understand your answer easily. so say there's a multiple choice question. you don't just want to say your answer is a, hope it . provide evidence and reasoning so that they know that that is the correct answer. a good explanation should have evidence, good reasoning, and your opinion on why you picked that. you don't want to look up their question on the internet and see if you can answer it. pick questions that you 100% know the answer to, so than that way you can provide a better explanation.

best of luck,
