a$-1.$ Identify the processing sequence that would result using $(1)$ First come, first served, $(2)$ Shortest processing time, $(3)$ Earliest due date, and $(4)$ Critical ratio. $($Hint: First determine the total job time for each job by computing the total processing time for the job and then adding in the setup time. All times and due dates are in hours.$)$
