A piece of new equipment has been proposed by engineers to increase the productivity of a certain manual welding operation.The investment cost is USD 25K, and the equipment will have a market value of USD 5K at the end of a study period of 5 years.Increased productivity attributable to the equipment will amount to USD 8K/year after extra operating costs have been subtracted from the revenue generated by the additional production.If the firm's MARR is 20% per year, is this proposal a sound one?Use the PW method.
