A new engineer is evaluating whether to use a higher-voltage transmission line. It will cost $250,000 more initially, but it will reduce transmission losses. The optimistic, most likely, and pessimistic projections for annual savings are $20,000, $15,000, and $8,000. The interest rate is 6%, and the transmission line should have a life of 30 years.
(a) What is the present worth for each estimated value?
(b) Use the range of estimates to compute the mean annual savings, and then determine the present worth.
(c) Does the answer to (b) match the present worth for the most likely value? Why or why not?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
