(c) Show that the difference between the amounts of work done in parts (a) and (b) is T1 delta SU .

     Interest rates must  (Click to select)  fall  rise  .

d. By how much will aggregate demand initially change if investors change their behavior because of this change in available credit?

     $  billion

Create a 350-word memo to management including the following:

• Describe the use of internal rate of return (IRR), net present value (NPV), and the payback method in evaluating project cash flows.
• Describe the break-even point and its importance.
• Describe the advantages and disadvantages of each method.

3) What is Rayleigh scattering? Given an excitation wavelength of 350 nm and an aqueous solution, at what wavelengths would you expect to see the Rayleigh scattering peaks in the emission spectrum?

4. Why are anti-Stokes shifts the least common phenomenon compared to Stokes or Rayleigh scattering?

JetAirways flight from Philadelphia to Boston has 350 seats. The high fare on the flight is $1000 and the restricted/low fare is $500. There is ample demand for the low fare class but high fare demand is uncertain. Demand for the high fare is normally distributed with mean 150 and standard deviation of 45. Further, the customers buy low fare tickets well in advance of high fare customers.

1. What is the expected revenue (in thousands) from high fare passengers when a booking limit of 200 is selected for the low fare tickets?

2. The JetAirways Customers’ Bill of rights states that “Customers who are involuntarily denied boarding shall receive $750 in addition to a ticket refund.” The RM department notices that the number of no-shows is normally distributed with a mean of 7.5 and standard deviation of 3. What is the maximum number of reservations in excess of plane capacity that the airline should accept?

In a minimum of 350 words, briefly compare and analyze two similar scenarios. Research scenarios that took place in the real world within the past five years that are similar to the scenario above. Select two and briefly compare how each case is similar to the scenario given and analyze how they differ. Based on the research you have found with similar scenarios, identify and describe two steps the victims of the data breach at ABC Bank can take after being alerted that their personal information was compromised.

This is the Scenario is was given and I'm having a hard time finding anything.

You work for B&SC Security, a security firm that is in charge of monitoring data breaches for ABC Bank. In the 5 years that you have worked for B&SC Security, you now manage a team of people; one of your tasks is to make sure that the data at ABC Bank is safe and the networks are secure. In the summer of 2018, ABC Bank experienced its biggest data breach. It has well over 10 million customers and from those 10 million customers, 6.5 million customers’ personal information such as names, addresses, social security numbers, bank account numbers, etc. were compromised. Hackers were able to find a weak spot in the security network and exploit it to gain access to the information which they stole. The attack went unnoticed for 90 days. Your security firm is starting to learn that some of the information that was stolen is now being used by the hackers to commit identity theft. ABC Bank has now reached out to you regarding the breach and to prevent future security breaches from occurring. Since then, you have been in constant communication with the President of ABC Bank and working closely with her to determine what can be done about the information that has been compromised, what changes need to be made in terms of security, and what future trainings and resources can be implemented to prevent another major data breach.

Your task is to prepare an analytical report to the President of ABC bank that determines the effects of the breach that occurred and investigate methods that can be used to prevent this magnitude of a breach in the future.

Question 10

AGD Co is a profitable company which is considering the purchase of a machine costing GHS320 million. If purchased, AGD Co would incur annual maintenance costs of GHS25 million. The machine would be used for the three years and at the end of this period would be sold for GHS50 million. Alternatively, the machine could be obtained under an operating lease for an annual lease rental of GHS120 million per year, payable in advance. AGD Co can claim capital allowances on a 25% reducing balance basis. The company pays tax on profits at an annual rate of 30% and all tax liabilities are paid one year in arrears. AGD Co has an accounting year that ends on 31 December. If the machine is purchased, payment will be made in January of the first year of operation. If leased, annual lease rentals will be paid in January of each year of operation.

Using an after-tax borrowing rate of 7%, evaluate whether AGD Co should purchase or lease the new machine.

Princess Cruise Company (PCC) purchased a ship from Mitsubishi Heavy Industry. PCC owes Mitsubishi Heavy Industry ¥500 million payable in one year. The current spot rate is ¥124/$ and the one-year forward rate is ¥110/$. Interest rate is 5% per annum in Japan and 8% per annum in the U.S. The 1-year call option on ¥ at the strike price of $.0081/¥ currently sells for a premium of .014 cents per Yen.

(1) Construct forward hedge for PCC and calculate the future dollar cost of meeting its ¥ obligation using this hedge.

(2) Construct money market hedge (MMH) for PCC and calculate the future dollar cost of meeting its ¥ obligation using MMH.

(3) How to hedge PCC’s foreign currency exposure in option market? Conduct cash flow analysis to examine the result of option hedge.

(4) At what future spot rate will PCC be indifferent between option hedge and forward hedge? Explain.
