A 50-meter tunnel must be constructed for a new city aqueduct. One alternative is to build a full- capacity tunnel now for $500,000. The other alternative is to build a half-capacity tunnel now for $300,000 and then to build a second parallel half- capacity tunnel 20 years hence for $300,000. The cost to repair the tunnel lining every 10 years is $20,000 for the full-capacity tunnel and $16,000 for each half-capacity tunnel. Determine whether the full- capacity tunnel or the half-capacity tunnel should be constructed now. Solve the problem by the conventional benefit-cost ratio analysis, using 4% interest rate and a 50-year analysis period. There will be no tunnel lining repair at the end of the 50 years.

Data for four mutually exclusive alternatives are given in the table below. Assume a life of 7 years and a MARR of 9%,

Can some one please help me to solve the following question. Please and thank you

Calisto Launch Services is an independent space corporation and has been contracted to develop and launch one oftwo different satellites. Initial equipment will cost $750,000 for the first satellite and $850,000 for the second.Development will take 5 years at an expected cost of $150,000 per year for the first satellite; $120,000 per year forthe second. The same launch vehicle can be used for either satellite and will cost $275,000 at the time of the launch5 years from now. At the conclusion of the launch, the contracting company will pay Calisto $2,500,000 for eithersatellite.Calisto is also considering whether they should consider launching both satellites. Because Calisto would haveto upgrade its facilities to handle two concurrent projects, the initial costs would rise by $150,000 in addition to thefirst costs of each satellite. Calisto would need to hire additional engineers and workers, raising the yearly costs to atotal of $400,000. An additional compartment would be added to…

A city has developed a plan to provide for future municipal water needs. The plan proposes an aqueduct that passes through 150 meters of tunnel in a nearby mountain. Two alternatives are being considered. The first proposes to build a full-capacity tunnel now for $556 000. The second proposes to build a half capacity tunnel now and a second identical half-capacity tunnel in 20 years. Each of half capacity tunnel costs $402 000. The maintenance cost of the tunnel lining for the full-capacity tunnel is $40 000 every 10 years, and for each half-capacity tunnel it is $32 000 every 10 years. The friction losses in the half-capacity tunnel will be greater than if the full-capacity tunnel were built. The estimated additional pumping costs for each half-capacity tunnel will be $2 000 per year. Using present worth method and a 7% interest rate, which alternative should be selected?

A firm is considering three mutually exclusive alternatives as part of an upgrade to an existing transportation network. Installed cost $40,000 $6,400 $30,000 $20,000 Net annual revenue $5.650 $5,250 Salvage value Useful life 20 years 20 years 10 years Calculated IRR 15.0% 18.2% 22.9% At EOY 10, alternative NI would be replaced with another alternative having the same installed cost and net annual revenues. If MARR is 10% per year, which alternative (if any) should be chosen? Use the incremental IRR procedure.
