Midwest Fabricators Inc. is considering an investment in equipment that will replace direct labor. The equipment has a cost of $132,000 with a $16,000 residual value and a 10-year life. The equipment will replace one employee who has an average wage of $34,000 per year. In addition, the equipment will have operating and energy costs of $5, 380 per year. Determine the average rate of return on the equipment, giving effect to straight-line depredation on the investment. If required, round to the nearest whole percent. Divide the estimated average annual income by the average investment. Average savings less depreciation expense less additional operating costs equals average annual income
