Professional Development Data Case Scenario$1$ Assume that today is November $27,2023.$ 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 $$38,000$ a year that she anticipates will grow at $3\%$ per year. Natasha hopes to retire at age $65$ and has just begun to think about the future. She has investigated a couple of education options and is asking for your help as a financial planning intern to determine the financial consequences associated with each option. Natasha has already been accepted to both programs and could start either one soon. Natasha has enough savings to finance either option. One alternative that Natasha is considering is attaining a certification in network design. This certification would automatically promote her to a Tier $3$ field service representative in her company. The base salary for a Tier $3$ representative is $$10,000$ more than what she currently earns, and she anticipates that this salary differential will grow at a rate of $3\%$ per year as long as she keeps working. The certification program requires the completion of $20$ Web$-$based courses and a score of $80\%$ or better on an exam at the end of the course work. She has learned that the average amount of time necessary to finish the program is one year. The total cost of the program is $$5000,$ due when she enrolls in the program. Because she will do all the work for the certification on her own time, Natasha does not expect to lose any income during the certification. Another option is going back to school for an MBA degree. With an MBA degree, Natasha expects to be promoted to a managerial position in her current firm. The managerial position pays $$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 the MBA. $1$ Slightly modified version of Berk$-$DeMarzo Chapter $4$ Data Case Problem. Determine the interest rate by going to the U$.$S$.$ Treasury Department website $($treasury$.$gov$)$ and selecting Data on the main menu. Then select Daily Treasury Par Yield Curve Rates under the Interest Rate heading and enter the appropriate year, $2023,$ and then search down the list for November $27$ to obtain the closing yield or interest rate she is earning. Use this interest rate as the discount rate for the remainder of this problem.

Create a timeline in Excel for her current situation, as well as for the certification program and MBA degree options, using the following assumptions:

Salaries for the year are paid only once, at the end of the year.

The salary increase becomes effective immediately after she graduates from the MBA program or is certified. That is$,$ because the increases become effective immediately, but salaries are paid at the end of the year, the first salary increase will be paid exactly one year after graduation or certification.
