Please answer the following questions. I spent hours trying to figure it out. Thanks.

JAZ Medical Supplies is implementing a new economic order quality (EOQ) inventory-control system and needs a good estimate of the cost to process a purchase order (PO); i.e, the order cost Co. It takes three total labor hours to process a PO. The average number of SKUs on a PO is three. The average wage for people working in the purchasing department is $33 per hour plus employee benefits of $4 per hour. Fixed costs for the purchasing department are $310,000 per year assuming 1,568 hours per employee per year workweek. Given this information, what is a good estimate of Co per SKU to use in an EOQ model? Round your answer to the nearest dollar. $ 235 per SKU Eight jobs have arrived in the following order: Job Processing Time Due Date 1 9 17 2 13 9 3 7 10 4 14 5 8 16 6 11 18 7 5 26 8 6 14 Find and compare the performance measures for the following sequencing rules using the Excel Sequencing template.
