Net Present Value Method and Present Value Index Diamond and Turf Inc. is considering an investment in one of two machines. The sewing machine will increase productivity from sewing 110 baseballs per hour to sewing 198 per hour. The contribution margin per unit is $0.46 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 $24 per hour. The sewing machine will cost $250,900, have an eight-year life, and will operate for 1,400 hours per year. The packing machine will cost $127,500, have an eight-year life, and will operate for 1,200 hours per year. Diamond and Turf seeks a minimum rate of return of 10% on its investments.

If required, round your answers to two decimal places. Sewing Machine Packing Machine Present value index C. If Diamond and Turf has sufficient funds for only one of the machines and qualitative factors are equal between the two machines, in which machine should it invest? (If both present value indexes are the same, either machine will grade as correct.) Sewing Machine
