Consider a $10,000 machine that will reduce pretax operating costs by $3,000 per year over the next five years. It will not require any changes in net working capital and is expected to have a salvage value of $1,000 in year 5. Assume 5-year MACRS and a tax rate of 34%. The discount rate is 10%. Should we accept the project? Please provide step by step solution with formula if possible.
