Problem 10-28 Equivalent Annual Cost [LO4]Light emitting diodes (LED) light bulbs have become required in recent years, but dothey make financial sense? Suppose a typical 60-watt incandescent light bulb costs $.43and lasts 1,000 hours. A 15-watt LED, which provides the same light, costs $3.30 andlasts for 12,000 hours. A kilowatt-hour of electricity costs $.119. A kilowatt-hour is 1,000watts for 1 hour. If you require a return of 10 percent and use a light fixture 500 hours peryear, what is the equivalent annual cost of each light bulb? (A negative answer shouldbe indicated by a minus sign.

9. A company that sells high-purity laboratory chemicals is considering investing in new equipment that will reduce cardboard costs by better matching the size of the products to be shipped to the size of the shipping container. If the new equipment will cost Php1M to purchase and install, how much must the company save each year for 3 years in order to justify the investment, if the interest rate is 10% per year? A Php66465.26 B Php88465.26 Php302114.80 Php402114.80
You are considering buying a piece of industrial equipment to automate a part of your production process. This automation will save labor costs by as much as $30,654 per year over 9 years. What is the maximum amount that you would pay for this equipment your interest rate is 10%? (your answer must be rounded off to the nearest dollar, i.e., no decimal places)
Light emitting diode (LED) light bulbs have become required in recent years, but do they make financial sense? Suppose a typical 60-watt incandescent light bulb costs $.50 and lasts for 1,000 hours. A 15-watt LED, which provides the same light, costs $3.65 and lasts for 12,000 hours. A kilowatt-hour is 1,000 watts for 1 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 9 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., 32.161616.) Break-even cost

Light emitting diode (LEDs) light bulbs have become required in recent years, but do they make financial sense? Suppose a typical 60-watt incandescent light bulb costs $.35 and lasts for 1,000 hours. A 15-watt LED, which provides the same light, costs $2.90 and lasts for 12,000 hours. A kilowatt hour of electricity costs $.111. A kilowatt-hour is 1,000 watts for 1 hour. However, electricity costs actually vary quite a bit depending on location and user type. An industrial user in West Virginia might pay $.04 per kilowatt-hour whereas a residential user in Hawaii might pay $.25.. You require a return of 9 percent and use a light fixture 500 hours per year. what is the break even cost per kilowatt-hour
The Wildwood Widget Company needs a milling machine for its new assembly line. The machine presently costs $85,000, but has a cost inflation rate of 2%. Widget will not need to purchase the machine for 3 years. If general inflation is expected to be 4% per year during those 3 years, determine the price of the machine. What is the present worth of the machinery if the market rate of interest for Widget is 25%?
A company is going to change all light bulbs of its buliding. The initial cost is 57000. all bulbs has been replaced at the same time. what if the bulbs have been replaced during 5 yrs period. Inflation rate is 3 percent. energy saving per yr is 6000 dollars. (compare replacement at the same time to the period of 5 yrs
You are considering buying a machine to produce widgets (again!). It takes you one year to finetune the machine so that it produces exactly the kind of widgets you want. The machine costs $40,000 today and produces 100,000 widgets in year 2. (You cannot produce in year 1 because you have to fine-tune the machine first.) Expected revenues are $1 per widget. The cost of producing widgets depends on the type of gas the machine uses. The machine uses one unit of gas per widget produced. In its current version the machine runs on a gas called "Gas A". The price of "Gas A" in year 2 is uncertain and will be known only at the beginning of year 2. This price will be either $0.75 or $0.25 per unit of gas with equal probability. All revenues and costs (except the cost of the machine) accrue at the end of year 2. The discount rate is 10%. a) What is the NPV of the project? b) The manufacturer of the machine offers you a device that can be attached to the machine. You will have to buy the device…
Light emitting diodes (LED) light bulbs have become required in recent years, but do they make financial sense? Suppose a typical 60-watt incandescent light bulb costs $.55 and lasts 1,000 hours. A 15-watt LED, which provides the same light, costs $3.90 and lasts for 12,000 hours. A kilowatt-hour of electricity costs $.131. A kilowatt-hour is 1,000 watts for 1 hour. If you require a return of 11 percent and use a light fixture 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.)
Light-emitting diode (LED) light bulbs have become required in recent years, but do they make financial sense? Suppose a typical 60-watt incandescent light bulb costs $.45 and lasts for 1,000 hours. A 7-watt LED, which provides the same light, costs $2.25 and lasts for 40,000 hours. A kilowatt-hour of electricity costs $.121, which is about the national average. A kilowatt-hour is 1,000 watts for 1 hour. If you require a 10 percent return and use a light fixture 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.) 60-watt light bulb LED light bulb Equivalent annual cost
