DVFS is a widely used approach for energy saving in todays computer systems. Assume that a system needs to run two real-time applications within 30 seconds as shown in the table below. Show the most energy-efficient schedule of the two applications. Compare its average power consumption (within 30 seconds) with the schedule that finishes each application at the earliest possible time. Assume that the system consumes zero power during idle time, and the supply voltage is proportional to the clock rate.

	Execution time (s)	Deadline (s)	Power (W)
Application A	6	24	3
Application B	3	6	5
