Answer the following questions:

A$.$ What cycle time is required to meet demand?

B$.$ Theoretically, how many stations are required to achieve this cycle time?

C$.$ Balance the assembly line assuming $5$ stations and using the longest$-$operating time rule, compute station time and idle time for each station.

D$.$ What is the efficiency of this line assuming that the cycle time is what you calculated for A$?$

E$.$ Suppose demand increases to $850$ units$/$day$,$ what's the new required cycle time and which stations need to be rebalanced if any?
