Complete the assignment using spreadsheet software to create the following: Make sure your formulas work correctly 1.) Perform a financial analysis for a project using the format provided in Figure 4-5. Assume that the projected costs and benefits for this project are spread over four years as follows: Estimated costs are $300,000 in Year 1 and $40,000 each year in Years 2, 3, and 4. Estimated benefits are $0 in Year 1 and $120,000 each year in Years 2, 3, and 4. Use a 7 percent discount rate, and round the discount factors to two decimal places. Create a spreadsheet or use the business case financials template on the Companion website to calculate and clearly display the NPV, ROI, and year in which payback occurs. In addition, write a paragraph explaining whether you would recommend investing in this project, based on your financial analysis. 2.) Create a weighted scoring model to determine grades for a course. Final grades are based on three exams worth 15 percent, 15 percent, and 25 percent, respectively; homework is worth 15 percent; and a group project is worth 30 percent. Enter scores for three students. Assume that Student 1 earns 100 percent (or 100) on every item. Assume that Student 2 earns 70 percent on each of the exams, 80 percent on the homework, and 95 percent on the group project. Assume that Student 3 earns 90 percent on Exam 1, 80 percent on Exam 2, 75 percent on Exam 3, 80 percent on the homework, and 70 percent on the group project. You can use the weighted scoring model template, create your own spreadsheet, or make the matrix by hand.
