Answer:
the overnight delivery is cheaper
Step-by-step explanation:
annual holding cost per day = $250,000 x 25% x 1/365 = $171.23
since you are saving 3 days of delivery time, you can save up to $171.23 x 3 = $513.69
the gain = savings - additional fee = $513.69 - $500 = $13.69
since you actually gain from this transaction, then you should pay the overnight freight
