Find incremental revenue as well and depreciation, please put the answer for each thing step by step and make it as clear as possible

One year ago, your company purchased a machine used in manufacturing for $110,000. You have learned that a new machine is available that offers many advantages; you can purchase it for $150,000 today. It will be depreciated on a straight-line basis over ten years and has no salvage value. You expect that the new machine will produce a gross margin (revenues minus operating expenses other than depreciation) of $40,000 per year for the next ten years. The current machine is expected to produce a gross margin of $20,000 per year. The current machine is being depreciated on a straight-line basis over a useful life of 11 years, and has no salvage value, so depreciation expense for the current machine is $10,000 per year. The market value today of the current machine is $50,000. Your company's tax rate is 45%, and the opportunity cost of capital for this type of equipment is 10%. Should your company replace its year-old machine
