Tribal Systems, Inc., is opening a new plant and has yet to decide on the type of process to employ. A labor-intensive process would cost $10,000 for tools and equipment and $14 for labor and materials per item produced. A more automated process costs $50,000 in plant and equipment but has a labor/material cost of $8 per item produced. A fully automated process costs $300,000 for plant and equipment and $2 per item produced. If process selection were based solely on lowest cost, for what range of production would each process be chosen?
