5. Fred, a city politician is advocating for a new dock and pier system along the river to boost local commerce. Acommittee appointed by the mayor, who opposes Fred, has prepared the following estimates: Input Variable Base CaseInitial building cost $6,000,000 Initial equipment cost $1,500,000 Annual benefits $3,000,000 Annual O&M cost $1,500,000 With a MARR of 6% and a project life of 10 years, perform a sensitivity analysis on the data using PW as theassessment metric. For each input, consider deviation of -10%, -5%, 0%, 5%, 10% from the base case. a. For eachdeviation of each input, calculate PW and show the result as a table similar to table 12.2 shown below. b. Show thesensitivity graph c. Which input has the biggest input on the PW?

6. David is opening an Aerial Adventure Park. He has three mutually exclusive design alternatives: Capital investment Annual receipts Annual expenses Design A $175,000 $115,000 $70,000 Design B $350,000 $150,000 $80,000 Design C $300,000 $125,000 $70,000 Market values are negligible. A 10-year study period is to be used and the MARR is 10% per year. Use the FW Method to determine which alternative should be chosen.
A certain masonry dam requires 200,000 m³ of gravel for its construction. The contractor found two possible sources for the gravel with the following data: Source A Source B Average distance, gravel pit to dam site 3 km 1.2 km Gravel cost/m³ at pit ➖➖➖➖➖ P10 Purchase price of pit P800,000 Road construction necessary P450,000 Overburden to be removed at P4.20/m³ 90,000m³ ➖➖➖➖➖➖ Hauling cost/m³/km P4 P4 What is the Total Cost of Source A
A business owner is comparing between three alternatives (A, B, and C) for their new project. A. Buy a new equipment with an initial cost of $120,000; annual operating cost of $7000; and salvage value of $5000. B. Buy a new equipment with an initial cost of $105,000; annual operating cost of $10500; and salvage value of $7000. C. Continue using the same equipment they already have with an annual operating cost of $25,000. Life of all alternatives is 12 years. With interest at 8% compounded annually, which alternative should the engineer recommend? Use future worth analysis.
Question 5 The best alternative in most engineering economy studies is the one that: O Is most politically correct. O Has the smallest cost O Has the fewest cost elements O Is easiest to implement. Will last the longest time
4. A rate of return analysis was conducted for the following alternatives, based on the table below.
