Suppose a company orders 10 pallets of bottled water, 14 oz. per bottle, and $0.05 per bottle. There are 2,000 bottles per pallet. Suppose they use a truckload carrier and it costs a flat rate of $1,000 for the transportation. So the purchase cost is $0.05 per bottle X 2,000 bottles per pallet X 10 pallets = $1,000. So the purchase cost plus the transportation cost is $2,000, hence, the total cost per bottle is $2,000 / 20,000 bottles = $0.10 per bottle. In this example, the company only ordered 10 pallets but a truck load has a capacity of about 20 pallets of bottled water. Instead, suppose they ordered 20 pallets of bottled water, the transportation cost will be the same but the purchase cost will now be $0.05 per bottle X 2,000 bottles per pallet X 20 pallets = $2,000. Hence the purchase cost plus the transportation cost is $3,000, so the total cost per bottle is $3,000 / 40,000 bottles ≈ $0.08 per bottle (rounded up from $0.075 per bottle). This demonstrates which of the following concepts?
