Better Plastics' management has recently been looking at a proposal to purchase a new plastic-injection-style molding machine. With the new machine, the company would not have to buy small plastic parts to use in production. The estimated useful life of the machine is 15 years, and the purchase price, including all setup charges, is $400,000. The residual value is estimated to be $40,000. The net addition to the company's cash inflow as a result of the savings from making the parts is estimated to be $70,000 a year. Better Plastics' management has decided on a minimum rate of return of 14 percent.
