Firm ABC is considering to invest in a project to reduce costs by $70,000 annually. The equipment costs $200,000, had a 4-year life (will be depreciated as a 3-year MACRS asset), requires no additional investment in net working capital, and has a salvage value of $50,000. The firms tax rate is 39% and the required return on investments in this risk class is 10%. What is the NPV and IRR of this project? (The MACRSs first three years depreciation rates in order are: 33.33%, 44.44% and 14.82%.)

Please include a step by step breakdown on a calculator due to needing to model this again and excel would not available (TI calculator steps are fine)! Thank you :)
