Assume that a new packaging machine costs $1,000,000 and promises to replace two workers (valued at $50,000 per year EACH) and save about $5,000 in power costs.if straight-line depreciation over 7 years is assumed, and the corporate tax rate is 30%, estimate the payback period (round answer to next year - e.g. if answer is 4.4 years, submit 5 years).
