Final answer:
The average transportation inventory for each option is 8 units for private ground and air transportation, and 1.14 units for public transportation.
Step-by-step explanation:
To calculate the average transportation inventory for each option, we need to consider the lead time for each transportation method. The lead time is the time it takes for the finished clothing to reach the retail location from the factory. Let's calculate the average transportation inventory for each option Private ground transportation The lead time is 3 days, so the average transportation inventory is 2,400 units / (300 working days per year * 3 days) = 8 units.Air transportation The lead time is 1 day, so the average transportation inventory is 2,400 units / (300 working days per year * 1 day) = 8 units.Public transportation The lead time is 7 days, so the average transportation inventory is 2,400 units / (300 working days per year * 7 days) = 1.14 units.Therefore, the average transportation inventory for each option is 8 units for private ground and air transportation, and 1.14 units for public transportation.
