Bruno's is analyzing two machines to determine which one it should purchase. the company requires a rate of return of 14.6 percent and uses straight-line depreciation to a zero book value over a machine's life. ignore bonus depreciation and taxes. machine a has a cost of $318,000, annual operating costs of $8,700, and a life of 3 years. machine b costs $247,000, has annual operating costs of $9,300, and a life of 2 years. whichever machine is purchased will be replaced at the end of its useful life. which machine should bruno's purchase and why?

(4 points) suppose the production function in the solow model is given by yt = ak¯ 3/4 t l 1/4 t . (a) what are the five equations and five unknowns that summarize the solow model? (b) show the transition dynamics in the solow model if ¯sy0 < ¯dk0. make sure you label the axes, curves, initial level of capital and steady-state level of capital. (c) solve for capital, output, capital per person, and output per person in the steady state. (d) if a¯ = 2, l¯ = 4, ¯s = 0.2, and ¯d = 0.05, calculate the steady-state level of capital and output per person.

You have learned that there are many ethical concerns surrounding genetic research, and it's important to be familiar with them. for this project, you will write a persuasive essay about an ethical question in biotechnology. directions the goal of a persuasive essay is to convince people to agree with you. it is important to support your opinion with facts. a persuasive essay is not simply a description of your beliefs. be sure to organize your information, give clear examples, and build your argument carefully. read the following genetics topics below. choose a topic and then decide what side you are on. remember that there is no "right" or "wrong" side. ethical questions often have many points of view. research your topic and write a 400 word persuasive essay. topic 1: should insurance companies have the right to learn the genetic profiles of the people they insure? topic 2: should employers have the right to learn the genetic profiles of the people they hire? are there special considerations for employees in jobs in which there is a high risk to others, such as airline pilots, doctors, or bus drivers? topic 3: should scientists who identify genes and create new genetic engineering techniques have the right to patent their methods for their own profit?

M. cotteleer electronics supplies microcomputer circuitry to a company that incorporates microprocessors into refrigerators and other home appliances. one of the components has an annual demand of 235 units, and this is constant throughout the year. carrying cost is estimated to be $1.25 per unit per year, and the ordering (setup) cost is $21 per order. a) to minimize cost, how many units should be ordered each time an order is placed? b) how many orders per year are needed with the optimal policy? c) what is the average inventory if costs are minimized? d) suppose that the ordering cost is not $21, and cotteleer has been ordering 125 units each time an order is placed. for this order policy (of q = 125) to be optimal, determine what the ordering cost would have to be.
