Carbon Emitters Inc. is looking at introducing a new pollution reduction technology into its manufacturing plant. The new equipment will cost $200,000 to purchase plus a further $15,000 for installation (cost will be capitalized). There are annual maintenance expenses of $5,000 to keep the equipment running properly.   The new equipment will allow the company to meet new government emission standards and Carbon Emitters will be able to sell pollution credits to other manufacturers for $50,000 annually over an expected seven-year timeline. Additional working capital of $10,000 will have to be injected.   CCA rate is 25% and the equipment will have a $30,000 salvage value. There will always be assets in this class. The firm is in the 30% tax bracket and has a weighted average cost of capital of 10%.   Should Carbon Emitters Inc. purchase the new equipment? Show your calculations.
