The golf ball machine will reduce labor cost. The labor cost saved is equivalent to $22 per hour. The stitching machine will cost $391,000, have an an eight-year life, and will operate for 1,400 hours per year. The golf ball machine will cost $98,300, have an an eight-year life, and will operate for 1,200 hours per year. Ball Sports Inc. seeks a minimum rate of return of 15% on its investments.
