  10. Production Schedule

  11. Reduction in Machine Time Total Time for machining is now 105 min. Cut our labor and machine cost by 40% New cost is $52.50 per Old Main New Per Unit cost of $87.43 Going to produce 18 this semester Accounting for 10 to be given away to faculty and group Going to sell 8 at $250 per Old Main Give Profit of around $200. New Findings & Decisions
