Light emitting diodes [LED] light bulbs haye become required in recent years, but do they make financial sense? Suppose a typical BIDwatt incandescent light bulb costs 35.4% and lasts 1,000 hours. A '15watt LED, which provides the same light, costs $3-55 and lasts for 12,009 hours- A kilowatthour of electricity costs $124. A kilowatthour is LOUD watts for 1 hour. If you require a return of 10 percent and use a light xture 500 hours per year, what is the equivalent annual cost of each light bulb? {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.} Ellwatt incandescent light bulb _ Light emitting diode {LED} light bulbs have become required in recent years, but do they make nancial sense? Suppose a typical 60watt incandescent light bulb costs $.39 and lasts for 1,000 hours. A15watt LED, which provides the same light, costs $3.10 and lasts for 12,000 hours- A kilowatthour is 1,000 watts for1 hour. Suppose you have a residence with a lot of incandescent bulbs that are used on average 500 hours a year. The average bulb will be about halfway through its life, so it will have 500 hours remaining {and you can't tell which bulbs are older or newer]. If you require a return of 11 percent, at what cost per kilowatt-hour does it make sense to replace your incandescent bulbs today? [A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to 6 decimal places, e.g., 31151615.} Your company has been approached to bid on a contract to sell 5,400 voice recognition [UR] computer keyboards a year for four years. Due to technological improyements, beyond that time they will be outdated and no sales will be possible. The equipment necessary for the production will cost $4.3 million and will be depreciated on a straight- line basis to a zero salvage value. Production will require an inyestment in net working capital of $455,000 which will be returned at the end of the projectr and the equipment can be sold for $425,000 at the end of production. Fixed costs are $530,000 per year, and yariable costs are $8? per unit. In addition to the contract, you feel your company can sell 13,000, 15,000, 10,100, and 11,000 additional units to companies in other countries over the next four years, respectively, at a price of $101 This price is xed. The tax rate is 22 percent, and the required return is 12 percent. Additionally, the president of the company will undertake the project only if it has an NP'U' of $150,000. What bid price should you set for the contract? {Do not round intermediate calculations and round your answer to 2 decimal places. e.g., 32.16.} Suppose we are thinking about replacing an old computer with a new one. The old one cost us 551340000; the new one will cost, $2,105,000. The new machine will be depreciated straight-line to zero oyer its fiyeyear life- It will probably be worth about $495,000 after five yea rs. The old computer is being depreciated at a rate of $334,000 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 $585,000; in two years, it will probably be worth $170,000. The new machine will saye us $355,000 per year in operating costs- The tax rate is 24 percent, and the discount rate is 9 percent. a-1.
