Chester Corporation is considering purchasing a new dry ice machine for his packaging business. the new machine will cost $75,000 but Chester expects the new machine will lead to him increasing his packaging business by an additional 1,000 per year. Each package CHester sells generates $200 in sales revenue with an incremental cost of $90 each. What is the after-tax cash flow per year of purchaing the new equipment, assuming a tax rate of 40-percent and a salvage value of zero after the ten years?
