Final answer:
To calculate the last mile cost per package, the cost of delivery labor should be divided by the total number of packages delivered. For mailroom tasks like weighing a box with books and documents, kilograms or grams should be used as the appropriate metric units of mass.
Step-by-step explanation:
When considering the last mile cost per package, it is important to understand the calculation is done to evaluate the efficiency and cost-effectiveness of the delivery process in a logistics operation. To calculate the last mile cost per package, you would divide the cost of delivery labor by the number of Total Packages delivered. This provides a clear metric to assess how labor costs are spread across the number of packages, aiding in financial planning and operational assessments for logistics and delivery companies. For Jesse, who works in the mailroom of a large company, choosing the appropriate metric unit of mass to weigh packages like the one containing 10 books and documents is crucial. In this situation, the metric unit that Jesse should use is kilograms (kg) or grams (g), depending on the total mass of the package, because these are the standard units for measuring weight in the metric system, suitable for packages typically sent through the mail.
