Eisenhower Communications is trying to estimate the first-year cash flow (at Year 1) for a proposed project. Note that this estimate is for capital budgeting purposes, so financing costs are ignored. The financial staff has collected the following information on the project: Sales revenues = $13.10 million, operating costs (excluding depreciation) = $9.30 million, depreciation = $2.20 million, interest expense = $2.40 million, tax rate = 37.0%, and WACC = 16.1%. Estimate the project's cash flow for the first year based on this data, then estimate the cash flow for the same project with the tax rate = 30.00%, then calculate the change in the cash flow estimate as a result of changing the tax rate.

Can someone help me solve step by step using a calculator method? Thank you
