Can you please solve it in step for me. Thank you so much.

You have to decide to invest or not for an expansion project. The project has an expected 5 years life. We assume that sales will be equal to $55,000 each year, variable cash operating expenses $18,000; and fixed operating expenses $24,000. Fixed operating expenses contain depreciations. We consider an investment outlay of $100,000 concerning fixed capital items that will be depreciated straight-line to zero over five years. We assume an annual investment in net working capital to t = 0 to t = 5 of $5,000. The expected after-tax salvage value is equal to $6,000. The tax rate is equal to 34%. 1) Determine the cash flows. 2) The expected rate of return is equal to 10%. What is the project NPV? 3) The IRR is equal to 12.14%. Is it compatible with the decision given by the NPV? Why
