immediate predecessors for producing one Micro Popcorn Popper are as follows:

$\backslash$table$[[$Task$,\backslash$table$[[$Performance$],[$Time $($mins$)]],\backslash$table$[[$Task Must Follow$],[$Task Listed Below$]]],[$A$,8,-],[$B$,10,$A$],[$C$,9,$A$,$ B$],[$D$,9,$B$,$ C$],[$E$,8,$C$],[$F$,4,$D$,$ E$]]$

a$)$ The theoretical minimum number of workstations $=4($round your response up to the next whole number$).$

b$)$ The assignment of tasks to workstations should be: $($Hint: Number workstations sequentially in terms of precedence relationships and combine any applicable tasks.$)$

$\backslash$table$[[$Task$,$Workstation #$],[$A$,$Station $1],[$B$,$Station $2],[$C$,$Station $3],[$D$,$Station $4],[$E$,$Station $5],[$F$,$Station $5]]$

Were you able to assign all the activities to workstations equivalent to the theoretical minimum workstation? No

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