Stanley, Inc. makes self-clinching fasteners for stainless steel applications. It expects to acquire new punching equipment 6 years from now. If the company sets aside $125,000 each year, determine the amount available in 4 years at an earning rate of 9% per year. Problem 6: A construction company wants to know how much to spend on maintenance for equipment each year for the next 6 years to be equivalent to part of its profit which equals $1 million 6 years from now. Assume the company's MARR is 20% per year. Problem 7: An arithmetic cash flow gradient series equals $1500 in year 1,$1700 in year 2, and amounts increasing by $200 per year through year 9 . At i=10% per year, determine the present worth of the cash flow series in year 0
