Individual industries will use energy as efficiently as it is economical to do so, and there are several incentives to improve the efficiency of energy
consumption. To illustrate, consider the selection of a new water pump. The pump is to operate 800 hours per year. Pump A costs $2,000, has an
overall efficiency of 80.58%, and it delivers 11 hp. The other available altemative, pump B, costs $1,200, has an overall efficiency of 44.39%, and
delivers 12.8 hp. Both pumps have a useful life of five years and will be sold at that time. (Remember 1 hp = 0.746 kW.)
Pump A will use SL depreciation over five years with an estimated SV of zero. Pump B will use the MACRS depreciation method with a class life
of three years. After five years, pump A has an actual market value of $410, and pump B has an actual market value of $180.
Using the IRR method on the after-tax cash flows and a before-tax MARR of 20%, is the incremental investment in pump A economically
justifiable? The effective income tax…

Tower City aims to construct a new bypass
between two main routes that will reduce
commuter travel time. The route will cost $15
million and will save 17,500 people $100 per
year in petrol costs. The path will be paved.
Every year, at a cost of $7,500, the surface must
be refinished. The road will be in use for the
next 20 years. Determine if Tower City should
construct the road. Money has an interest rate
of 8%(ɛ = interest rate) .

A new crane will cost $20,000, will last for 8 years, and will have a $4,000 MV at that time. Operating and maintenance costs are $1,000 per year for the new crane.

- The state of Glottamora has $300 million remaining in its budget for the current year. One alternative is to give Glottamorans a one-time tax rebate. Alternatively, two proposals have been made for state expenditures of these funds.

Projected benefits of the new power plant are as follows: Years Benefits per Year ($ Millions) 1 - 5 0 6 - 20 60 The second alternative is to undertake a job retraining program, also costing $100 million and generating the following benefits: Years Benefits per Year ($ Millions) 1 - 5 60 6 - 10 42 11 - 20 12 The state Power Department argues that a 5 percent discount factor should be used in evaluating the projects because that is the government’s borrowing rate.

It has two options for reducing its emissions. Option 1: the company can spend $32,000 annually on a new filtration system, which will cut its emissions to 120 tons. Option 2: In addition to the filtration system, the company could implement a new recycling technology that will cost $24,000 per year and cut emissions to 30 tons. For each ton of reduced emissions, the company saves $240 . First, use marginal analysis to determine which option will save the company the most money. Then, calculate how much money the company will save and enter it in the box below, rounding your answer to two decimal places if necessary.arrow_forwardYou are about to buy a piece of equipment (machine Alpha) for a project.

- Five years ago a dam was constructed to impound irrigation water and to provide flood protection for the area below the dam. Last winter a 100-year flood caused extensive damage both to the dam and to the surrounding area. This was not surprising, since the dam was designed for a 50-year flood. The cost to repair the dam now will be $250,000. Damage in the valley below amounts to $750,000. If the spillway is redesigned at a cost of $250,000 and the dam is repaired for another $250,000, the dam may be expected to withstand a 100-year flood without sustaining damage. However, the storage capacity of the dam will not be increased and the probability of damage to the surrounding area below the dam will be unchanged. A second dam can be constructed up the river from the existing dam for $1 million. The capacity of the second dam would be more than adequate to provide the desired flood protection. If the second dam is built, redesign of the existing dam spillway will not be necessary, but…arrow_forwardA manufacturer has been ordered to stop discharging acidic waste into the city sewer.
