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 $1.90 to install/replace. Installation
of a single CFL costs $2.90, 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 10% 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…

- 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,…arrow_forwardSandra and Mary live next to each other. Sandra has a dog that she walks every day. Sandra has to walk past Mary's front lawn and her dog always pees on Mary's flowers, which causes them to eventually die. Mary will move in a few months but, until then, she estimates she will spend $100 on flowers to replace the ones that die as a result of the daily visits from Sandra's dog. The only solution to this problem is a $50 fence that can be put around Mary's flowers that will protect them from Sandra's dog. a. What term do economists use for the consequences of Sandra's daily walks in this setting? b. Is it socially optimal to have the fence put around the flowers in this case? Why or why not? c. What does the Coase theorem say about how the social optimum could be achieved? Explain what an agreement between Sandra and Mary would look like if Mary has the right to not be bothered by her neighbour's dog.arrow_forwardFive years ago a dam was constructed to impound irrigation water and to provide flood protection for the area below the dam. Last winter a 100-year flood caused extensive damage both to the dam and to the surrounding area. This was not surprising, since the dam was designed for a 50-year flood. The cost to repair the dam now will be $250,000. Damage in the valley below amounts to $750,000. If the spillway is redesigned at a cost of $250,000 and the dam is repaired for another $250,000, the dam may be expected to withstand a 100-year flood without sustaining damage. However, the storage capacity of the dam will not be increased and the probability of damage to the surrounding area below the dam will be unchanged. A second dam can be constructed up the river from the existing dam for $1 million. The capacity of the second dam would be more than adequate to provide the desired flood protection. If the second dam is built, redesign of the existing dam spillway will not be necessary, but…arrow_forward
- Construction on your custom home is complete and now the yard must be landscaped. The landscape contractor has estimated that 8 cubic yards of dirt and 3 cubic yards of sand will be required to level the yard and provide proper drainage. Dirt is priced at $35 per cubic yard and sand is priced at $27 per cubic yard. She has measured the yard and calculated the area needing sod to be 3600 ft2. Sod is sold in rolls that measure 90 ft? at a cost of $10 each per roll. Shrubbery installation will cost an additional $2500. Estimate the cost of the landscaping.arrow_forwardNow we have that AVC achieves it's minimum when q = 3. Find the minimum value that the AVC reaches by plugging in q=3 to AVC (q) = q? – 6q + 20. You can verify that this value is right in a couple of ways: (1) check your desmos plot to make sure that the y-coordinate at the minimum matches AVC(3). The other is to compute MC(3), which should be the same as AVC(3). Set p-AVC(3), the value you just found. This should be your shit-down price.

He must replace a worn-out copy machine that is used for black-and-white copying. He is considering two machines, and each of these has a monthly lease cost plus a cost for each page that is copied. Machine 1 has a monthly lease cost of $639, and there is a cost of $0.030 per page copied. Machine 2 has a monthly lease cost of $747, and there is a cost of $0.045 per page copied. Customers are charged $.08 per page copied. If Benny expects to make 75,000 copies per month, what would be the monthly cost for each machine?

- = 2. The cost of operating a jet-powered commercial (passenger- carrying) airplane varies as the three-halves (3/2) power of its velocity; specifically, Co kny3/2, where n is the trip length in miles, k is a constant of proportionality, and vis velocity in miles per hour. It is known that at 400 miles per hour, the average cost of operation is $300 per mile. The company that owns the aircraft wants to minimize the cost of operation, but that cost must be balanced against the cost of the passengers' time (CC), which has been set at $300,000 per hour. At what velocity should the trip be planned to minimize the total cost, which is the sum of the cost of operating the airplane and the cost of passengers' time?arrow_forwardFor the following economic calculations, write the factors (multipliers) that should be used, Q2. in (i) using the parameter values, and in (ii) calculate the result by showing your computations.

Heating and cooling bills will be about 50% less than in a similar wood-frame home in Vermont. An ICF home will be approximately 10% more expensive to construct than a wood-frame home. A typical 2,000 square-foot home costs $120 per square foot to build with wood framing in Vermont and costs $200 per month (on average) to heat or cool.What is the IRR on the incremental investment in an equivalent-sized ICF home? The home’s residual value with both framing methods in 20 years is expected to be $280,000.arrow_forward
