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 $.53 and lasts for 1,000 hours. A 15-watt LED, which provides the same light, costs $3.80 and lasts for 12,000 hours. A kilowatt hour of electricity costs $.129. 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? (Do not round intermediate calculations and round your answer to 6 decimal places, e.g., 32.161616.) Break-even cost

A company selling widgets has found that the number of items sold, x, depends upon the price, p at which 80000 they're sold, according the equation z : (0.6p + 1)? Due to inflation and increasing health benefit costs, the company has been increasing the price by $0.04 per month. Find the rate at which revenue is changing when the company is selling widgets at $7 each. Revenue is decreasing by dollars per month Hint: Give your answer as a positive value.
A typical tube-style incandescent light bulb lasts for 1,000 hours and is available to consumers for $3.30 per bulb. A manufacturer has produced a tube-style halogen light bulb that gives the same amount of light as the incandescent bulb but lasts for 1,400 hours. The halogen bulb also uses less energy than the incandescent bulb, saving the consumer $0.50 in electricity costs for every 1,000 hours of light-bulb use. (a) What is the value to the customer of the manufacturer’s tube-style halogen light bulb to consumers who are currently buying tube-style incandescent light bulbs? Show your work. (b) If the manufacturer’s variable costs for producing these halogen light bulbs are $2.25 per bulb, specify the price ceiling and the price floor for these halogen bulbs. Explain your reasoning. (c) According to the course material, what is meant by the strategic prominence of price? If the halogen light bulb manufacturer wants to make price the lead activity in the marketing mix,…
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 $2.00 each will provide the same illumination as standard 60-Watt ILBs costing $0.50 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 $2.00 to install/replace. Installation of a single CFL costs $3.00, and it will also be used 1,000 hours per year. Electricity costs $0.12 per kiloWatt hour (kWh), and you decide to compare the two lighting options over an 8-year study period. If the MARR is 12% per year, compare the economics of the two alternatives and write a brief report of your findings for the boss.
The economically destructive price spike of 2007–2008 occurred when spare production capacity fell below 1 mbpd, causing a run-up in oil price from $50 to $145 per barrel. An issue for world oil spare capacity is the internal consumption of OPEC producers. OPEC production has ranged between 30 and 33 mbpd since 2004. Internal use is currently about 25% of total OPEC production, but it is growing by 2% per year. The internal consumption growth is largely for nonelastic end uses such as electricity generation, water treatment, and new buildings. If the current world spare capacity is 2 mbpd and the OPEC total production does not increase beyond 33 mbpd, how many years will it take for the spare capacity to fall below 1 mbpd again?
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.
Eduardo has $7,000 in savings. His bank pays 6% interest per year on savings. He withdraws all of his savings to purchase a machine for his business. At the end of the year, he can resell the machine for $1,000. Based on this information, what are Eduardo's economic costs for the year, in dollars? Enter a number only, no $ sign.
Planning for a major redesign, Itumeleng collected data at her store on several consecutive Saturday mornings. She noticed that customers arrived at the checkout at a rate of approximately 100 per hour. Fully 20 percent of the customers had 10 items or less. Those people took about 2 minutes to serve on average, while customers with more than 10 items took about 4 minutes to process. Itumeleng expects service time to improve when universal price code readers are installed in the new design. Help Itumeleng with her design for the system,
You and one of your classmates are considering setting up a prescription delivery service for local residents in Mount Pearl. In order to start the business you will need to purchase a car for $7,200 which you expect you will be able to sell for $3,600 at the end of every two years (you'll have to purchase a new equivalent car at that time). Insurance costs are $560 for each six months of operation, starting immediately, and advertising costs (flyers, newspaper ads, etc.) are estimated to be $110 per month. All calculations are performed using 4 significant figures. The big question is how many customers you will have, but you figuring on setting a fee of $2 per delivery, which will be payable by your clients at the end of each month. Assuming a stable interest rate of 6% per year, compounded monthly what is the break even number of deliveries per month?

Jenny Tanaka wants to buy a new car, and the annual gasoline expense is a major consideration. Her present car gets 25 miles per gallon (mpg), and she is considering purchasing a new car that gets 40 mpg. Jenny now drives about 12,000 miles per year and pays $3.25 per gallon of gasoline. She therefore calculates an annual gasoline consumption of 480 gallons for her 25 mpg car (12,000 miles/25 mpg) compared to 300 gallons consumed per year for the 40 mpg car (12,000 miles/40 mpg). Since driving the higher- mileage car would use 180 gallons less per year, Jenny estimates the new car will save her $585 in gasoline expense per year (180 gallons 3 $3.25 per gallon). Suppose Jenny buys the 40 mpg car. According to economic theory, Jenny's actual annual savings on gasoline will be 7 1 C 1 U C VI 10 V K W S TACAZEC 10 GUNS TOMBER 2 than her initial estimate of $585.
Electricity is produced with water according to the function: E = 5 + 5W-1W² where E = kilowatt-hour and W = gallons of water. Water costs $0.02 per gallon. Electricity can be sold on the grid for $0.10 per kWh (kilowatt-hour). How much water should be purchased?
