a$)$ The theoretical minimum number of workstations $=5($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.$)$

Were you able to assign all the activities to workstations equivalent to the theoretical minimum workstation? Yes

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