A casting costs $25. the burden cost on the machine that finishes the casting is $450 per hour, time for the part on the machining center is 50 minutes, and the setup time is 4 hours. If the castings are machined in lot sizes of 25. what percentage of the part cost is due to setup time? (Enter your answer without the percent % sign.) A study to replace the operator in the previous problem (Problem 3) with a robot indicated that the burden rate for the cell would increase to $1.150 per hour the part machining time would drop to 12 minutes and the setup time would drop to 2.2 hours. If the casting cost is $20, what it the part cost for a lot size of 20 in this new automated cell (Enter your answer without the dollar $ sign) A work cell includes two 30-inch-square pallets for raw casting and finished castings, an operator's work area used to insert bushings into the machined casting that is 30 inches by 48 inches, a tool rack that covers 9 square feet wide walkways and machine clearances that cover 18 square feet, and the production machine that measures 51 inches by 114 inches. Determine the manufacturing space ratio for the work cell. A company has an annual cost for goods sold of $3 million and an average inventory value of $900,000. What are the inventory turns for this company
