Answer:
D. They might order a greater number of gallons with jugs or with barrels, depending on various factors like the demand rate, ordering cost, and holding cost.
Step-by-step explanation:
Let us assume the following things
D be the demand rate
P be the Unit cost
H be the holding cost per gallon per months
S be the ordering cost
Now the economic order quantity is
EOQ units = Q = √(2DS ÷ (H))
Therefore, the order quantity would be based upon demand rate, ordering cost and holding cost.
So the last option is correct
