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

(i want answer in step by step) 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 S .41 and lasts 1, 000 hours. A 15 - watt LED, which provides the same light, costs $3.20 and lasts for 12, 000 hours. A kilowatt - hour of electricity costs $.117. A kilowatt-hour is 1,000 watts for 1 hour. If you require a return of 9 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.)
A university spent $2 million to install solar panels atop a parking garage. These panels will have a capacity of 700 kilowatts (kW) and have a life expectancy of 20 years. Suppose that the discount rate is 20%, that electricity can be purchased at $0.10 per kilowatt-hour (kWh), and that the marginal cost of electricity production using the solar panels is zero. Hint: It may be easier to think of the present value of operating the solar panels for 1 hour per year first. Approximately how many hours per year will the solar panels need to operate to enable this project to break even? 8,214.28 5,867.34 2,346.94 4,693.87 If the solar panels can operate only for 5,281 hours a year at maximum, the project break even. Continue to assume that the solar panels can operate only for 5,281 hours a year at maximum. In order for the project to be worthwhile (i.e., at least break even), the university would need a grant of at least blank

Suppose I have computed the cost of carbon per mile for my car at 0.011 per mile. Assume that the interest rate is 5% and that I drive the car 30,000 miles per year. What is present value of the carbon expense for five years? You will need to use the PV function in Excel or a financial calculator. In Excel the present value of a stream of monetary cash flows is given by -PV(rate, number of payments, payment amount) where rate is the interest rate. We enter the payment in Excel as a positive number. You can also compute the carbon cost per year and then discount those five values back to the present.
1.15 Refer to Problems 1.13 and 1.14. If charles lackey's utility costs remain constant at $500 per month, labor at $8 per hour, and cost of ingredients at $0.35 per loaf, but Charles does not purchase the blender suggested in Problem 1.14, what will the productivity of the bakery be? What will be the percent increase or decrease?
9. Assume a constant marginal cost of $0.01/kwh for hydro and $0.09/kwh for natural gas given installed capacity. Assume that installed capacity can be bought at the beginning of the year and sold at the end of the year at the same price and that the discount rate or interest rate is 8.76% and that there are 8760 hours in a year. A kilowatt of natural gas capacity costs $1000 and a kilowatt of hydro capacity costs $10,000. Because you can buy and sell the capacity at the same price this means that the fixed cost of installed capacity is just the opportunity cost of capital, or the interest rate times the purchase price of the capacity.a. What is the average total cost of producing 8760 kilowatt hours in a year using one kilowatt of installed hydro capacity?b. What is the average total cost of producing 8760 kilowatt hours in a year using one kilowatt of installed natural gas capacity?
Shunda is a calculator assembly company, purchase a full set of the calculator parts, assembled into a calculator to sell in the market. In recent years, the price of the calculator has remained steady at 60 yuan/units, the basic data of the input and output of shunda in 2013are listed in the table below: Hourly wage is 6 yuan per hour, price of parts is 25 yuan per set, power consumption is paid by 0.6 yuan per watt, the extract depreciation of equipment is 3 yuan per hour, and Shunda spends fixed costs 10000 yuan per month to pay all of the regular fee According to the above data, is it possible to estimate the production function and cost function (TC, TVC, AC and AVC)?

The owner of Barb’s Burgers has suggested the firm should invest in more moderntechnology and created a list of potential changes she thinks may be helpful as aninvestment. She has asked you to analyze the four potential choices and comment onwhat this would change in terms of cost: Hire a firm to create an online system to allow customers to order even when theyare not physically at Barb’s Burgers. This would allow for people to ensure theirorders were input correctly for those who are pickier eaters. The online systemwould need to be integrated into the point of sales system to track orders for thekitchen Question: Argue how each of these is likely to change the cost of the firm once implemented (i.e. are any of these a fixed cost or a variable cost). How this adjust theamount of labour and/or capital currently necessary for the firm? Would the technology be a general technology, labour-saving, or capital-saving?
Mutale, a lawyer, working for a large law firm and earning K60, 000 per year, is contemplating setting up his own law practice. He estimates that renting an office would cost K10,000 per year, hiring a legal secretary would cost K20,000 per year, and purchasing supplies, paying for electricity, telephone and so forth would cost another K5, 000 per year. The lawyer estimated that his total revenue for the year would be K100, 000. a) How much are the explicit costs of running the law firm? b) How much are the implicit costs? c) How much are the economic costs? d) Should the lawyer go ahead to set up the law firm?
