A factory is running an assembly line for $7\mathrm{.}5$ hours per day and must produce $300$ units each day in order to keep up with demand. The tasks, their time requirements, and preceding tasks are included to the left. Use this information to compute the required cycle time, compute the number of required stations, and then balance the assembly line using the 'longest task time' as your primary rule and 'most dependent tasks' for tiebreaks. Finally, compute the line's efficiency based on the cycle time calculated above and answer the short answer questions below.
