on an assembly line, and there are six steps that need to be completed for assembly. The demand for the control panel is $4,800$ units per $40-$hour workweek:

$\backslash$table$[[$Task$,\backslash$table$[[$Performance Time$],[($seconds$)]],$Predecessors$],[$A$,20,],[$B$,28,$A$],[$C$,15,$A$],[$D$,14,$A$],[$E$,10,$B$,$ C$],[$F$,28,$D$,$ E$]]$

a$)$ Given the demand, the cycle time for the production of the new control panel $=$ seconds $($round your response to one decimal place$).$

b$)$ The theoretical minimum number of workstations $=($round your response up to the next whole number$).$

$\backslash$table$[[$Task$,$Workstation #$],[$A$,$V$],[$B$,],[$C$,],[$D$,],[$E$,],[$F$,]]$

Were you able to assign all the tasks to the theoretical minimum number of workstations? $$

d$)$ The total idle time per cycle for the process $=$ seconds $($enter your response as a whole number$).$

e$)$ The efficiency of the assembly line with $5$ workstations $=\%($enter your response as a percentage rounded to one decimal place$).$
