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. Assume that both installation cost and cost of the bulbs occur at the…

Your answer is partially correct.
A state department of health is considering a public awareness campaign to encourage vaccination. It determines that the cost of this
campaign would be $760,000 per year for the next 6 years. It estimates that the campaign would reduce rates of illness and
communicable disease. At the end of the first year of the campaign, the resulting savings would be $1,150,000; the savings would
decrease by $120,000 each of the following 5 years. Assuming a discounting factor of 8%, compute the benefit cost ratio.

- 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.arrow_forward= 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_forwardA large company in the communication and publishing industry has quantified the relationship between the price of one of its products and the demand for this product as Price = 160 -0.02 × Demand for an annual printing of this particular product.

Demand is not expected to be more than 4,000 units per year. The maximum profit that can be achieved is $144,313. (Round to the nearest dollar.)

- Assume a company expects to sell 6 million packages of Pop-Tarts Gone Nutty! in the first year after introduction but expects that 70 percent of those sales will come from buyers who would normally purchase existing Pop-Tart flavors (that is, cannibalized sales). The price for a package of Pop-Tarts Gone Nutty! is $1.30 and its variable cost is $0.65, when the price for a package of original Pop-Tart is $1.10 with variable cost of $0.30. Assuming the sales of regular Pop-Tarts are normally 300 million packages per year and that the company will incur an increase in fixed costs of $450,000 during the first year to launch Gone Nutty! will the new product be profitable for the company?

- Cameron sells premium steak at the local market. He has a lot of customers due to the promising taste and texture of his steak. One kilogram of his premium steak costs $80.50. However, it would only cost $68.50 per kilogram if a customer buys 3 kilograms and $58.50 per kilogram if a customer buys 5 kilograms. Cameron can supply 100 kilograms of premium steak in a day, but his supply only lasts for an hour and a half. Which of the following statements is true? With this pricing scheme, Cameron is extracting all the consumer surplus. Cameron is basing his pricing scheme on the maximum amount a customer is willing to pay for his premium steak. Cameron is using third degree price discrimination by charging different prices for different "blocks" of kilograms for his premium steak. Cameron receives a larger revenue and profts with this pricing scheme compared to charging a single lower price for larger quantities. None of the above are true.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.
