Chapter 5, Problem 51P
A computer call center is going to replace all of its incandescent lamps with more energy-efficient fluorescent lighting fixtures. The total energy savings are estimated to be $1,875 per year, and the cost of purchasing and installing the fluorescent fixtures is $4,900. The study period is five years, and terminal market values for the fixtures are negligible. (5.8)

Marian Plunket owns her own business and is considering an investment. If she undertakes the investment, it will pay $5,560 at the end of each of the next 3 years. The opportunity requres an initial investment of $1,390 plus an additional investment at the end of the second year of $6,950. What is the NPV of this opportunity if the interest rate is 2.2% per year? Should Marian take it?
Suppose that you purchase a tractor for $170,000 and sell it in 10 years for $50,000. What is the annualized cost (capital recovery) if your required return on capital is 12%?
An aircraft hangar requires a new high-efficiency HVAC system for environmental control and reducing
heating and cooling expenses. The cost of the HVAC system is $5.0 million, and the annual savings are
expected to be $400,000. The useful life of the HVAC system is 20 years, and its residual value is zero.
a) What is the simple payback period?
b) What is the internal rate of return? (Note: You can use the tables in the book or Excel to find the
IRR, but in either case show work and/or cut & paste a spreadsheet. If using the tables an
approximate answer will be acceptable)

- Should Jim sell his Minivan? Jim's 1998 minivan is quite functional, but it only averages 20 miles per gallon (mpg). He has found a somewhat newer vehicle (roughly the same functionality) that averages 26 mpg. He can sell his current minivan for $2800 and purchase the newer vehicle for $4,000. Assume a cost of gasoline $4.00 per gallon. How many miles per year must Jim drive if he wants to recover his investment in three years? Assume an interest rate of 6%, zero salvage value for either vehicle after three years, and identical maintenance cost.arrow_forwardSuppose that you have just completed the mechanical design of a high-speed automated palletizer that has an investment cost of $3,800,000. The existing palletizer is quite old and has no salvage value. The market value for the new palletizer is estimated to be $430,000 after nine years. One million pallets will be handled by the palletizer each year during the nine-year expected project life. What net savings per pallet (i.e., total savings less expenses) will have to be generated by the palletizer to justify this purchase in view of a MARR of 18% per year? Use the AW method. Click the icon to view the interest and annuity table for discrete compounding when the MARR is 18% per year. The net savings required to be generated by the new palletizer to justify its purchase are $ per pallet (Round to the nearest cent)arrow_forwardANSWER: ERR (i %) = 23.71%arrow_forward

Interestingly, the F-T process was used in World War II to make gasoline and other fuels. The U.S. military can save one billion gallons per year of foreign oil by blending its jet fuel with F-T products. If the government expects inflation to average 3% per year, what is the equivalent uniform annual savings in fuel? The government's MARR is 7% per year, the study period is 40 years, and one gallon of jet fuel costs $2.80. The AW is $_______billion.arrow_forward
