Please make it as formal as possible. Thanks

Assume that today is August 5, 2015. Natasha Kingery is 30 years old and has a Bachelor of Science degree in computer science. She is currently employed as a Tier 2 field service representative for a telephony corporation located in Seattle, Washington, and earns $38,000 a year that she anticipates will grow at 3% per year. Natasha hopes to retire at age 65 and has just begun to think about the future. DATA BASE Part 2 Interest Rates and Valuing Cash Flows Natasha has $75,000 that she recently inherited from her aunt. She invested this money in 10year Treasury bonds. She is considering whether she should further her education and would use her inheritance to pay for it. She has investigated a couple of options and is asking for your help as a financial plan_ ning intern to determine the nancial consequences associated with each option. Natasha has already been accepted to two programs and could start either one soon. One alternative that Natasha is considering is attaining a certication in network design. This certication would automatically promote her to a Tier 3 eld service rem-e- sentative in her company. The base salary for a Tier 3 representative is $10,000 more than the salary of a Tier 2 representative, and she anticipates that this salary differential will grow at a rate of 3% a year for as long as she remains employed. The certication program requires the completion of 20 Web-based courses and a score of 80% or better on the nal exam. She has learned that the average amount of time necessary to nish the program is one year. The total cost of the program is $5000, due when she enrolls in the program, Because she will do all the work for the certication on her own time, Natasha does not expect to lose any income during the certification process. Another Option is going back to school for an MBA degree. With an MBA degree, Natasha expects to be promoted to a managerial position in her current rm. The mana- gerial position pays $20,000 a year more than her current position. She expects that this salary differential will also grow at a rate of 3% per year for as long as she keeps working. The evening program, which will take three years to complete, costs $25,000 per year, due at the beginning of each of her three years in school. Because she will attend classes in the evening, Natasha doesn't expect to lose any income while she is earning her MBA if she chooses to undertake it. 1. Determine the interest rate Natasha is currently earning on her inheritance by going to Yahoo! Finance (http:/l nance.yahoo.com) and clicking the 10 Yr Bond link in the Market Summary section or enter "TNX in the symbol Iookup field. Then go to the Historical Prices link and enter the appropriate date, August 5, 2015, to obtain the closing yield or interest rate that she is earning. Use this interest rate as the discount rate for the remainder of this problem. 2. Create a timeline in Excel for Natasha's current situation, as well as the certication program and MBA degree options, using the following assumptions: a. Salaries for the year are paid only once, at the end of the year. b. The salary increase becomes effective immediately upon graduating from the MBA program or being certied. That is, because the increases become effective imme- diately but salaries are paid at the end of the year, the rst salary increase will be paid exactly one year after graduation or certication. 3. Calculate the present value of the salary differential for completing the certication program. Subtract the cost of the program to get the value of undertaking the certi- fication program. 4. Calculate the present value of the salary differential for completing the MBA degree- (Ealculate the present value of the cost of the MBA program. Based on your calcula- tions, determine the value of undertaking the MBA. 5. Based 'on your answers to Questions 3 and 4, what advice would you give to Natasha? What if the two programs are mutually exclusive? If Natasha undertakes one of the programs, there is no further benet to undertaking the other program. Would your advrce change
