A factory uses the EOQ formula to decide its production batch size, where the ordering/setup cost is directly based on the setup time. Currently, with a setup time of 100 minutes, the optimal batch size is 300. In order to reduce the optimal batch size to 30, how long must the setup time be, assuming demand and inventory holding costs are kept the same? Select one: a. 1.00 minute b. 10.00 minute of 3.33 minute d33.33 minute
