Your boss has asked you to evaluate the economics of replacing 1,000 60-Watt incandescent light bulbs (ILBs) with 1,000 compact fluorescent lamps (CFLs) for a particular lighting application. During your investigation you discover that 13-Watt CFLs costing $2.002.00 each will provide the same illumination as standard 60-Watt ILBs costing $0.500.50 each. Interestingly, CFLs last, on average, eight times as long as incandescent bulbs. The average life of an ILB is one year over the anticipated usage of 1,000 hours each year. Each incandescent bulb costs $2.002.00 to install/replace. Installation of a single CFL costs $3.003.00, and it will also be used 1,000 hours per year. Electricity costs $0.120.12 per kiloWatt hour (kWh), and you decide to compare the two lighting options over an 8-year study period. If the MARR is 1212% per year, compare the economics of the two alternatives and write a brief report of your findings for the boss. Assume that both installation cost and cost of the bulbs occur at the beginning of each year and that the electricity expense is incurred at the end of each year for eight years.

The gilbert instrument corporation is considering replacing the wood steamer it currently uses to shape guitar sides. the steamer has 6 years of remaining life. if kept, the steamer will have depreciaiton expenses of $650 for five years and $325 for the sixthyear. its current book value is $3,575, and it can be sold on an internet auction site for$4,150 at this time. if the old steamer is not replaced, it can be sold for $800 at the endof its useful life. gilbert is considering purchasing the side steamer 3000, a higher-end steamer, whichcosts $12,000 and has an estimated useful life of 6 years with an estimated salvage value of$1,500. this steamer falls into the macrs 5-year class, so the applicable depreciationrates are 20.00%, 32.00%, 19.20%, 11.52%, 11.52%, and 5.76%. the new steamer is fasterand allows for an output expansion, so sales would rise by $2,000 per year; the newmachine's much greater efficiency would reduce operating expenses by $1,900 per year. to support the greater sales, the new machine would require that inventories increase by$2,900, but accounts payable would simultaneously increase by $700. gilbert's marginalfederal-plus-state tax rate is 40%, and its wacc is 15%.a. should it replace the old steamer? b. npv of replace = $2,083.51
