How can I solve this question? In addition, how can I explain whether I would recommend investing in this project, based on the financial analysis?

Perform a financial analysis for a project. 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. What would a spreadsheet to calculate and clearly display the NPV, ROI, and year in which payback occurs look like?
