The grocery store has introduced a pilot packaging service for customer pick-up. For the program, the store employs one worker to prepare the customers package. The computer system estimates how much time is required to prepare each order. The customer may specify a desired due date for package pickup. If the store can ensure the due date, then the customer is charged $6. If the order is ready after the customers due date, the customer is charged $4. The data below shows 6 customer orders with processing time in minutes and customer due date in minutes elapsed from the store opening time.
