FORMULAS:
A new engineer is evaluating whether to
use a larger diameter pipe for a water line.
The pipe will cost $376,183 more initially but
will reduce pumping costs. The optimistic,
most likely, and pessimistic projections for
annual savings are $30,000, $20,000, and
$5000, with respective probabilities of 20%,
50%, and 30%. The interest rate is equally
likely to be 6% or 8% (use 7% as most likely),
and the water line should have a life of 40
years.
a) Find the PW for the pessimistic case, the
most likely case, and the optimistic case.
Then determine the Expected PW based on
these.
b) Find the expected annual savings and
the expected interest rate. Determine the
Expected PW based on these.
Eng. Economic Q1. Would a dollar tomorrow be worth more to you today when interested is 20% or 10%?

Group of answer choices
The cost and benefits to Gawanza will be lowest in the last few years of implementing this plan.
The cost and benefits to Gawanza will be highest in the last few years of implementing this plan.
The cost will be the highest and benefits the lowest in year ten.

- QUESTION 1 Mixtastic's Founder-CEO is discussing the timing of the launch of its mix-at-home cocktail kit with potential investors. "With a big push and a full-time commitment from myself, we could roll out the subscriptions right away and make $100K in profit per year. Or, if I run the business part-time as a side project, we could start selling three years from now." Assuming Mixtastic has an 80% chance of survival each year, how much would it be worth to start earning profit immediately, rather than in three years? It's worth $80K more if it launches immediately. It's worth $244K more if it launches immediately. It's worth $376K more if it launches immediately. It's worth $1 million more if it launches immediately.arrow_forward10) a) What are the probability distributions for the annual benefit and life for the following project? The annual benefit's most likely value is $7000 with a probability of 60%. There is a 30% probability that it will be $4000, and the highest value that is likely $9,000. A life of 6 years is twice as likely as a life of 9 years. b) The project has a first cost of $25,000. The firm uses an interest rate of 8%. Assume that the probability distributions for annual benefit and life are unrelated or statistically independent. Calculate the probability distribution for the PW c) The first cost of the project is $25,000. Use the expected values for annual benefits and life to estimate the present worth. Use an interest rate of 8%. d) Use the probability distribution function of the PW to calculate the EV(PW). Does this indicate an attractive project? F) Using the probability distribution for the PW, calculate the PW's standard deviation.arrow_forwardPlease show work on Excel. A new engineer is evaluating whether to use a larger diameter pipe for a water line. The pipe will cost $327,089 more initially but will reduce pumping costs. The optimistic, most likely, and pessimistic projections for annual savings are $30,000, $20,000, and $5000, with respective probabilities of 20%, 50%, and 30%. The interest rate is most likely to be 7%, but is equally likely to be 6% or 8%, and the water line should have a life of 40 years. Find the expected annual savings and the expected interest rate. Determine the Expected PW based on these. Hint: Based on the different saving and their probabilities, find the expected value of savings. Then find the expected value of the interest rate (each option has equal probability). Then find the PW using these values.arrow_forward
