Problem 2Groundwater wells are known to begin pumping sand once it becomes exploited (old), and thismay damage the subsequent water treatment processes. To solve this problem, two alternatives areproposed:A new well can be drilled at a capital cost of $385,000 with minimal operating andmaintenance expenses of $20,500 per year.A settling tank can be constructed ahead of the treatment processes which will cost$190,000 to build and $32,100 per year to operate and maintain.The salvage value of either option at EOY 20 is 10% of the capital investment. Using a MARR of7%:(a) Which alternative is better for the 20-year study period (using the present worth method)?(b) Confirm the answer of (a) using the future worth method (state the future worth for eachof the alternatives and make a decision based on these values)?

A mining company is considering a new project. Because the mine has received a permit, the project would be legal; but it would cause significant harm to a nearby river. The firm could spend an additional $10 million at Year 0 to mitigate the environmental problem, but it would not be required to do so. Developing the mine (without mitigation) would require an initial outlay of $60 million, and the expected cash inflows would be $20 million per year for 5 years. If the firm does invest in mitigation, the annual inflows would be $21 million. The risk-adjusted WACC is 15%. Should this project be undertaken? 1. The project should not be undertaken under the "no mitigation" assumption. 2. The project should be undertaken only under the " no mitigation" assumption. 3. The project should not be undertaken under the "mitigation" assumption. 4. Even when mitigation is considered the project has a positive NPV, so it should be undertaken. 5. Even when mitigation is considered the project has a…
An electric utility is considering a new power plant in northern Arizona. Power from the plant would be sold in the Phoenix area, where it is badly needed. Because the firm has received a permit, the plant would be legal; but it would cause some air pollution. The company could spend an additional $40 million at Year 0 to mitigate the environmental problem, but it would not be required to do so. The plant without mitigation would require an initial outlay of $269.87 million, and the expected cash inflows would be $90 million per year for 5 years. If the firm does invest in mitigation, the annual inflows would be $93.62 million. Unemployment in the area where the plant would be built is high, and the plant would provide about 350 good jobs. The risk adjusted WACC is 16%. Calculate the NPV and IRR with mitigation. Enter your answer for NPV in millions. For example, an answer of $10,550,000 should be entered as 10.55. Negative values, if any, should be indicated by a minus sign. Do not…
Consider a firm that mines minerals in northern BC. The initial cost to develop the mine is $10 Million. The cost to operate the mine is $5 Million per year. The mine operates only three years starting one year after its development. However, the mine pollutes a river causing a decline of the salmon population. In response, the net benefits from salmon fishing decline from $1 Million to $0.5 Million per year. The damage to the river lasts forever. Assume an interest rate of 10%. What is the present value of the private costs? Type your answer... Consider a firm that mines minerals in northern BC. The initial cost to develop the mine is $10 Million.

Rust Industrial Systems Company is trying to decide between two different conveyor belt systems. System A costs $350,000, has a 4-year life, and requires $141,000 in pretax annual operating costs. System B costs $430,000, has a 6-year life, and requires $135,000 in pretax annual operating costs. Both systems are to be depreciated straight- line to zero over their lives and will have zero salvage value. Whichever project is chosen, it will not be replaced when it wears out. The tax rate is 22 percent and the discount rate is 8 percent. Calculate the NPV for both conveyor belt systems. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) System A System B Which conveyor belt system should the firm choose? ○ System B O System A

The Logan Well Services Group is considering two sites for storage and recovery of reclaimed water. The mountain site (MS) will use injection wells that cost $4.2 million to develop and $280,000 per year for M&O. This site will be able to accommodate 150 million gallons per year. The valley site (VS) will involve recharge basins that cost $11 million to construct and $400,000 per year to operate and maintain. At this site, 720 million gallons can be injected each year. If the value of the injected water is $3.00 per thousand gallons, which alternative, if either, should be selected according to the B/C ratio method? Use an interest rate of 8% per year and a 20-year study period. The B/C ratio is . Select alternative (Click to select) neither of the alternatives mountain site valley site .
A remotely located air sampling station can be powered by solar cells or by running an above ground electric line to the site and using conventional power. Solar cells will cost $17,200 to install and will have a useful life of 5 years with no salvage value. Annual costs for inspection, cleaning, and other maintenance issues are expected to be $2,000. A new power line will cost $25,500 to install, with power costs expected to be $1,000 per year. Since the air sampling project will end in 5 years, the salvage value of the line is considered to be zero. At an interest rate of 10% per year and using an AW analysis, what must be the first cost of the above ground line to make the two alternatives equally attractive economically? The first cost of the above ground line to make the two alternatives equally attractive economically is $-1
Dwight Donovan, the president of Walton Enterprises, is considering two investment opportunities. Because of limited resources, he will be able to invest in only one of them. Project A is to purchase a machine that will enable factory automation: the machine is expected to have a useful life of four years and no salvage value. Project 8 supports a training program that will improve the skills of employees operating the current equipment. Initial cash expenditures for Project A are $102,000 and for Project B are $33,000. The annual expected cash inflows are $32,178 for Project A and $10,865 for Project B. Both investments are expected to provide cash flow benefits for the next four years. Walton Enterprises' desired rate of return is 4 percent. (PV of $1 and PVA of $1 ) (Use appropriate foctor(s) from the tables provided.) Required o. Compute the net present value of each project. Which project should be adopted based on the net present value approach? b. Compute the approximate…
The Cebu City plans to increase the capacity of her existing water transmission lines. Two plans are under consideration. Plan A requires the construction of a parallel pipeline, the flow being maintained by gravity. The initial cost is P197,342,811 and the life is 40 years, with an annual operating cost of P8,450,154 for the 1st 20 years and P13,297,046 for the next 20 years. Plan B requires the construction of a booster pumping station costing P100M with the life of 40 years. The pumping equipment cost an additional amount of P25M, it has a life of 20 years and a salvage value of P2M. The annual operating cost is P5M. Using the Present Value (PV) Method and an interest of 21% cpd. annually, what is the PV of Plan A?
A community is looking to build a dam over a stretch of river that is currently being used for recreation. The dam will generate electricity. The dam will have a useful life of 50 years after which its reservoir will be full of sediment and the dam will need to be removed. The following are the characteristics of the dam:Initial cost: $350,000,000Electricity produced: 200,000 MWh per year at $150/MWh Value of recreation lost: $20,000,000 per year a. If the social discount rate is a constant 2% per year, is the dam a good idea? Show your work and explain your rationale.

Oil from a particular type of marine microalgae can be converted to biodiesel that can serve as an alternate transportable fuel for automobiles and trucks. If lined ponds are used to grow the algae, the construction cost will be $13 million and the maintenance & operating (M&O) cost will be $2.1 million per year. If long plastic tubes are used for growing the algae, the initial cost will be higher at $18 million, but less contamination will render the M&O cost lower at $0.41 million per year. At an interest rate of 10% per year and a 5-year project period, which system is better, ponds or tubes? Use a present worth analysis.
