D'Angelo's brown sugar factory has a production capacity of 400 pounds/hr. Since freshness is a top priority, D'Angelo only produces sugar when an order arrives to his factory - he does not produce any brown sugar to finished goods inventory. The factory opens at 8am and runs until all orders are complete for the day. If D'Angelo gets an order for 1200 pounds at 8am, an order for 200 pounds at 12pm, and a final order for 600 pounds at 2pm, then what time can his factory shut down for the day? (a) 11am (b) 12:30pm (c) 1pm (d) 3pm (e) 3:30pm
