Swift Oil Company is considering investing in a new oil well. It is expected that the oil well will increase annual revenues by $134,000 and will increase annual expenses by $76,000 including depreciation. The oil well will cost $449,000 and will have a $11,000 salvage value at the end of its 10-year useful life. Calculate the annual rate of return. (Round answer to 2 decimal places, e. g. 12.47.)

White truffles are a very prized and rare edible fungus that grow naturally in the countryside near alba, italy. suppose that it costs $200 per day to search for white truffles. on an average day, the total number of white truffles (t) found in alba is t = 20x − x 2 , where x is the number of people searching for white truffles on that day. white truffles can be sold for $100 each. if there is no regulation, how many more people will be searching for white truffles than the socially optimal number?
