Jolt - K The soda machine outside the lecture hall sees a steady stream of customers throughout the day. The machine takes 4 seconds to deliver a can of carbonated sugar water once the button is pressed and students generally know what they want from the machine - the average feeding of the machine takes two seconds. Over the course of a twelve hour lecture day, students arrive at the rate of 500 per hour. When idle, the soda machine's CPU is tasked with participating in the Enigma@home project. If it can try 5 different solutions per second, how many solutions can it propose over the course of a twelve hour day?
