able plastics, an injection-molding firm, has negotiated a contract with a national chain of department stores. plastic pencil boxes are to be produced for a 2-year period. if the firm invests $62,000 for special removal equipment to unload the completed pencil boxes from the molding machine, one machine operator can be eliminated saving $32,000 per year. the removal equipment has no salvage value and is not expected to be used after the 2-year production contract is completed. the equipment would be serviceable for about 15 years. what is the payback period? should able plastics buy the removal equipment?
