Restoring balance to the nitrogen cycle is one of the challenges facing engineers. Improving the effectiveness and economical use of fertilizer has been identified as an important step in the right direction. Engineers have designed an improved way to transport fertilizer and then to apply it directly at the point where crops are grown. Further development, assessment, and optimization of the necessary equipment is estimated to require $220,000 in year 1, increasing by a gradient of $80,000 in each of years 2, 3, and 4. Then, it will begin to decrease by $95,000 in years 5, 6, 7, and 8. Interest is 14% per year. Part c What gradient series, beginning with the $220,000 in year 1 is equivalent to these cash flows?

Required information Eight years ago, Ohio Valley Trucking purchased a large-capacity dump truck for $116,000 to provide short-haul earth- moving services. The company sold it today for $45,000. Operating and maintenance costs averaged $10,900 per year. A complete overhaul at the end of year 3 costs an extra $3600. Calculate the annual cost of the truck at i= 8% per year. The annual cost of the truck is $- 503,717 per year. 13

Chinese economic growth is the outstanding feature of the world economic scene over the past two decades. In 2018, U.S. output was $20.5 trillion, and Chinese output in 2017was $13.5 trillion. Suppose that from 2017, the output of China grows at an annual rate of 7.9% per year, whereas the output of the United States grows from 2018 at an annual rate of 2.2% per year. Using these assumptions and a spreadsheet, calculate and plot U.S. and Chinese output from 2017 or 2018 over the next 50years. The level of U.S. output in 50 years will be The level of Chinese output in 50 years will be $ places.) trillion (Round your response to two decimal places) trillion (Round your response to two decimal How many years will it take for China to have a total level of output equal to that of the United States? A. 4.7 years B. 20.5 years C. 12.6 years D. 6.3 years

3) Find the rate of return (IRR-Ch16.3) on a project that will cost $100,000 today and $400,000 in 3 years from today, BUT will return $50,000 at the end of every year for 11 years (4)

Required information Assume that 25 years ago your dad invested $320,000, plus $32,000 in years 2 through 5, and $49,000 per year from year 6 on. Determine the annual retirement amount that he can withdraw forever starting next year (year 26), if the $49,000 annuity stopped at year 25. The interest rate being 14% per year. The annual retirement amount is determined to be $
