Diamond and Turf Inc. is considering an investment in one of two machines. The sewing machine will increase productivity from sewing 130 baseballs per hour to sewing 234 per hour. The contribution margin per unit is $0.36 per baseball. Assume that any increased production of baseballs can be sold. The second machine is an automatic packing machine for the golf ball line. The packing machine will reduce packing labor cost. The labor cost saved is equivalent to $28 per hour. The sewing machine will cost $221,000, have a 10-year life, and will operate for 1,400 hours per year. The packing machine will cost $141,700, have a 10-year life, and will operate for 1,200 hours per year. Diamond and Turf seeks a minimum rate of return of 15% on its investments.
