In a replacement analysis for a vacuum seal on a spacecraft, the following data are known about the challenger: the initial investment is $11,000; there is no annual maintenance cost for the first three years, however, it will be $2,000 in each of years four and five, and then $5,000 in the sixth year and increasing by $3,500 each year thereafter. the salvage value is $0 at all times, and marr is 10% per year. a. what is the economic life of this challenger? b. what is the euac corresponding to the economic life in part a ?

As a general rule, when accountants calculate profit they account for explicit costs but usually ignorea. certain outlays of money by the firm.b. implicit costs.c. operating costs.d. fixed costs.

Draw a flowchart for a process of interest to you, such as a quick oil-change service, a factory process you might have worked in, ordering a pizza, renting a car or truck, buying products on the internet, or applying for an automobile loan. identify the points where something (people, information) waits for service or is held in work-in-process inventory, the estimated time to accomplish each activity in the process, and the total flow time. evaluate how well the process worked and what might be done to improve it.

The monthly demand equation for an electric utility company is estimated to be p equals 60 minus left parenthesis 10 superscript negative 5 baseline right parenthesis x, where p is measured in dollars and x is measured in thousands of killowatt-hours. the utility has fixed costs of $3 comma 000 comma 000 per month and variable costs of $32 per 1000 kilowatt-hours of electricity generated, so the cost function is upper c left parenthesis x right parenthesis equals 3 times 10 superscript 6 baseline plus 32 x. (a) find the value of x and the corresponding price for 1000 kilowatt-hours that maximize the utility's profit. (b) suppose that the rising fuel costs increase the utility's variable costs from $32 to $38, so its new cost function is upper c 1 left parenthesis x right parenthesis equals 3 times 10 superscript 6 baseline plus 38 x. should the utility pass all this increase of $6 per thousand kilowatt-hours on to the consumers?
