Installing low thermal emissivity windows (low-e windows) on buildings can contribute to energy conservation. Installing low-ewindows on a school building is estimated to cost $10,000. The windows are expected to last 6 years and have no salvage value at thattime. The energy savings from the windows are expected to be $2,525 in the 1st year. After the 1st year, the savings are expected toincrease by $125 each year due to escalating fossil fuel costs. MARR is 15% per year and annual worth is the preferred measure ofeconomic worth. Which Excel® entry should you use to determine the annual worth of installing the low-e windows?-NPV (15 %,6,10000)+NPV( 15%,6,- NPV ( 15%,2525,25252525,2525,25252525))O-PMT( 15%,6,10000) + PMT( 15 %,6,- NPV ( 15%, 0,125,2 125,3 125,4 125,5*125))+2525O-PMT(15,6,10000)+PMT(15,6,PMT(15,0,125,2 125,3 125,4*125,5*125))+2525-PMT(15%.6.10000)+PMT (15% , 6 , NPV ( 15%, 2525,2 2525,2525,2525,2525))

Street lighting fixtures and their sodium vapor bulbs for a two-block area of a large city need to be installed at a first cost (investment cost) of $100,000. Annual maintenance expenses are expected to be $6,650 for the first 9 years and $9,500 each year thereafter upto 30 years. With an interest rate of 8% per year, what is the present worth cost of this project? Choose the closest answer below OA. The present worth cost of the project is $236,701. OB.

Suppose we are thinking about replacing an old computer with a new one. The old one cost us $1,620,000; the new one will cost, $1,949,000. The new machine will be depreciated straight-line to zero over its five-year life. It will probably be worth about $405,000 after five years. The old computer is being depreciated at a rate of $336,000 per year. It will be completely written off in three years. If we don't replace it now, we will have to replace it in two years. We can sell it now for $531,000; in two years, it will probably be worth $153,000. The new machine will save us $363,000 per year in operating costs. The tax rate is 23 percent, and the discount rate is 10 percent. a-1. Calculate the EAC for the the old computer and the new computer. (A negative answer should be indicated by a minus sign.

10. Triple Crown is considering installing a new cooler (equipment) in order to increase the volume and variety of beverages they can offer. The new cooler will cost $26,000. It is expected to last 7 years but only if the cooler is overhauled (REPAIRED) at a cost of $4,000 at the end of year 4. The new cooler is expected to have a $2,000 salvage value at the end of 7 years. The new cooler is expected to generate additional revenues of $15,000 per year with an increase in expenses of $9,000 per year. Triple Crown's discount rate is 12%. What is the net present value of this investment opportunity? Should they invest in the cooler? Hint: determine the PV of each item.

Lumberjack Power, operator of a nuclear power plant, is planning to replace its current equipment with some that is more environmentally friendly. The old equipment has annual operating expenses of $6750 and can be kept for 8 more years. The equipment will have a salvage value of $4000, if sold 8 years from now, and has a current market value of $24,000, if it is sold now. The new equipment has an initial cost of $62,000 and has estimated annual operating expenses of $6250 each year. The estimated market value of the new equipment is $19,000 after 8 years of operation. If the company's MARR is 16% per year, should the equipment be replaced? Use a study period of 8 years and the present worth method.
The Oviedo Company is considering the purchase of a new machine to replace an obsolete one. The machine being used for the operation has a book value and a market value of zero. However, the machine is in good working order and will last at least another 10 years. The proposed replacement machine will perform the operation so much more efficiently that Oviedo's engineers estimate that it will produce after-tax cash flows (labor savings) of $6,000 per year. The after-tax cost of the new machine is $30,000, and its economic life is estimated to be 10 years. It has zero salvage value. The firm's WACC is 10%, and its marginal tax rate is 25%. Should Oviedo buy the new machine? Oviedo (should or Should not) purchase the new machine.
Cor's Dog House is considering the installation of a new computerized pressure cooker for hot dogs. The cooker will increase sales by $10,100 per year and will cut annual operating costs by $11,750. The new system will also prompt a $4,900 increase in net working capital. The system will cost $60,200 to purchase and install. This system is expected to have a 4-year life and will be depreciated to zero using straight-line depreciation and have no salvage value. The tax rate is 21 percent and the required return is 10.5 percent. What is the NPV of purchasing the pressure cooker? OCF = $ CFO = S CF4=$ NPV = It It It It It 11 11

If this money is spent immediately, the mine will generate $21.5 million for the next 10 years. After that, the coal will run out and the site must be cleaned and maintained at environmental standards. The cleaning and maintenance are expected to cost $1.9 million per year in perpetuity. What does the IRR rule say about whether you should accept this opportunity? If the cost of capital is 8.1%, what does the NPV rule say? Use the graph below to determine the IRR(s) in the problem.
