Red Sox Corporation wants to purchase a new machine for $350,000. Management predicts that the machine can produce sales of $205,000 each year for the next 5 years. Expenses are expected to include direct materials, direct labor, and factory overhead (excluding depreciation) totaling $85,000 per year. The firm uses straight-line depreciation with no residual value for all depreciable assets. Pique's combined income tax rate is 35%. Management requires a minimum after-tax rate of return of 10% on all investments. What is the payback period for the new machine (rounded to nearest one-tenth of a year)? (Assume that the cash inflows occur evenly throughout the year.)
