Answer:
c. less than $45,000
Explanation:
total cost with 180 metric tons of order
= $18000*11000 + 20%*36000*180/2 + 36000*11000/180
= $198000000 + $648000 + $2200000
= $200848000
total cost with 235 metric tons
= 18000*11000 + 7200*235/2 + 36000*11000/235
= 198000000 + 846000 + 1685106
= $200531106
net savings = $316894
Therefore, The annual amount that Net Steels can save by ordering as per the EOQ instead of its conventional order is less than $45,000.
