An ice cream business is paying an effective tax rate of 25%. The company is considering the purchase of a new turbo churn for $25,000. This churn is a special handling device for food manufacture and has an estimated life of 4 year and a salvage value of $5,000. The new churn is expected to increase net income by $8,000 per year for each of the 4 years of use. If the ice cream company works with an after tax MARR of 10% and uses 3-year MACR depreciation, should the company buy the churn? Consider after-tax net present worth analysis
