Can this please be solved with excel formulas? Thank you in advance

Bolden Health System Inc. has decided to acquire a new electronic health record system for its Rio hospital. The system receives clinical data and other patient information from nursing units and other patient care areas, then either displays the information on a screen or stores it for later retrieval by physicians. The system also permits patients to call up their health record on Bolden's website. The equipment costs $1,000,000, and, if it were purchased, Bolden could obtain a term loan for the full purchase price at a 10 percent interest rate. Although the equipment has a six-year useful life, it is classified as a special-purpose computer, so it falls into the MACRS three-year class. If the system were purchased, a four-year maintenance contract could be obtained at a cost of $20,000 per year, payable at the beginning of each year. The equipment would be sold after four years, and the best estimate of its residual value at that time is $200,000. However, since real-time display system technology is changing rapidly, the actual residual value is uncertain. As an alternative to the borrow-and-buy plan, the equipment manufacturer informed Bolden that Consolidated Leasing Center would be willing to write a four-year guideline lease on the equipment, including maintenance, for payments of $260,000 at the beginning of each year. Bolden's marginal federal-plus-state tax rate is 40 percent. You have been asked to analyze the lease-versus-purchase decision, and in the process to answer the following questions: a. What is the present value cost of owning the equipment? b. What is the present value cost of leasing the equipment? c. What is the net advantage to leasing (NAL)? d. Answer again the above questions one at a time to see the effect of the change on NAL. That is, starting with the original numbers you used for questions a. and b., what is the NAL if: - pre-tax interest rate increases to 12 percent - the tax rate falls to 34 percent - maintenance cost increases to $25,000 per year - residual value falls to $150,000 - the system price increases to $1,050,000 ? e. Do the changes in d. make leasing more or less attractive? Explain.

Net advantage to leasing: PV cost of leasing PV cost of owning NAL To obtain the values in the purple cells, you may for example replace ONE AT A TIME the pre-tax interest rate, tax rate, maintenance cost, residual value, and system price with their respective new value, and then report into the related purple cells each updated set of results obtained in c. ONE AT A TIME means to make sure to put back the original value of each item before updating the value of the next item. When done, make sure to put back the original value of the last item (that is System price) so that the solutions for a., b., and c. display correctly. Example: To obtain the values in D74 and in D75, replace the pre-tax interest rate in C37 by 12%. Copy and paste the new results in D66 and D67 into D74 and D75, respectively. Put back 10% in C37 before replacing the tax rate in C38 by 34%. Repeat similarly the process to fill in the other purple cells. e. (Narrative)
