Considering Lockheed’s past and some of the ethics related issues they (and other defense contractors) experienced in past decades, identify and describe what you consider to be some of the key turning points in the organization that ultimately led to a genuine effort to institute a working ethics program at Lockheed. What were some of the things they did to initiate the company’s ethics program and why do you think so much effort needs to be expended to affect cultural change at a company like Lockheed?
A real estate agent is considering changing her cell phone plan. There are three plans to choose from, all of which involve a monthly service charge of $20. Plan A has a cost of $.45 a minute for daytime calls and $.20 a minute for evening calls. Plan B has a charge of $.55 a minute for daytime calls and $.15 a minute for evening calls. Plan C has a flat rate of $80 with 200 minutes of calls allowed per week and a charge of $.40 per minute beyond that, day or evening.
a. Determine the total charge under each plan for this case: 120 minutes of day calls and 40 minutes of evening calls in a week.
b. Prepare a graph that shows total weekly cost for each plan versus daytime call minutes.
c. If the agent will use the service for daytime calls, over what range of call minutes will each plan be optimal?
d. Suppose that the agent expects both daytime and evening calls. At what point (i.e., percentage of call minutes for daytime calls) would she be indifferent between plans A and B?
