hi I have done few of my questions but I need to verify the answers. please someone help.

Q1. As the CFO of your company, it falls to you to make the final decision on large expenditures. Recently, your controller has proposed purchasing a new computer system at a cost of $50,000. He believes the system will deliver savings of $60,000 in the accounting department and could be useful to other departments as well. Your treasurer takes a decidedly different view of the proposal. She claims that the company will have to borrow money to buy the computer system, and this will cost $11,000 in interest. As well, she is concerned the amount of savings promised by the controller won't materialize. Should you purchase the computer system? b. For situations like the one described in Part (a) where differing views are expressed by individuals, it is possible that an individual may, in part, be acting in self-interest. Is it possible that one of the two individuals in question (the controller or the treasurer) could be acting in self-interest in this instance? If so, comment on the ethical aspects of this behaviour. Q2. Paul and Maria want to have enough money to travel around the world when they retire. They both just turned 30 and will retire when they turn 60. They earn a total of $9,000 after taxes each month. Their monthly expenditures include $3,000 in mortgage payments, $850 in car payments, and $1,450 in other expenses. They approached a fund manager and decided to invest the rest of their income at the end of each year. They expect to earn a 10 percent expected annual rate of return for each of the next 30 years. When they retire, they will sell their cottage for an expected price of $50,000. a. b. Q3. Bert has just been hired by your company as a summer co-op student and has been assigned to assist you. Bert is puzzled about why your company is calculating IRR and payback periods for investment projects. According to Bert's finance textbook, NPV gives the best measure of the impact of a project on shareholder wealth. a. b. c. Q4. Your client is confused. He owns shares in the Whistler Snow-Making Company and wants you to explain your recommendation. Both of you agree on the following: WSMC has an expected return of 12 percent, a standard deviation of 9 percent, and beta of 1.25; the expected return on the market is 8 percent, with standard deviation of 3 percent; and the risk-free rate is 4 percent. Your client has a basic understanding of the CAPM and, based on the capital market line, feels he should sell the stock. However, you are recommending that he buy more of the stock (or at least hold what he has). Explain your recommendation to your client. Assuming CAPM is valid, can we have a situation where stock A has a required rate of return of 15 percent and a beta of 1.4, and stock B has a required rate of return of 20 percent and beta of 1.2? Q5. You are forecasting the returns for a plumbing supply company, the PVC Company, which pays a current dividend of $10. The dividend is expected to grow at a rate of 3 percent. You have identified two public companies, ABC and VJK, that appear to be comparable to PVC. ABC has the same total risk as PVC and a beta of 1.2. VJK, in contrast, has a very different total risk but the same market risk as PVC. VJK's beta is 0.75. The market risk premium is 5 percent and the risk-free rate is 1 percent. a. b. Q6. you have been hired as a consultant to the x-ray G lass corporation XGC. XGC is in the process of deciding whether to invest in a project to manufacture x-ray machines for airports. The manufacturing process is not very different from the company's current line of business. The management of XGC has produced certain estimates about the new project.
