(EOQ model) Division X is growing and is in constant need of trained employees. The demand rate for trained employees is relatively constant at 5 each month. The division can run a training program that costs $5,000 per offering regardless of class size. Students graduate with a certificate and a $100/week pay raise. The raise is operative even if they attended the training before the new job is open and they continue with their old job (until they are reassigned to a higher-skilled position). What class size is optimal and how many classes should be offered every year? [Hint: You need not consider anybody%u2019s salary or career after they take their higher-skilled job.]
