Problem 1 - Norman Companu\y
_____________
a)EOQ = \/ 2 x 8,000 x 40
25
= 160 units

Ordering cost =No of orders x ordering cost
=8,000 x 40
160
=2,000

Carrying cost=Average inventory x 25
=160 x 25
2
=2000

Problem 2 – Abner Company
_____________________________________________ a) EOQ = 2 (number of units required annually)(cost of order)
carrying cost per unit
___________________
2 x (1,200x 3) x 200
= 25
____________
1,440,000
= 25

= 240 units

b) Number of orders in a year = annual requirements
EOQ
= 3,600/240
= 15 orders

c) Average inventory based on EOQ = EOQ/2
= 240/2
= 120

d) Total carrying cost =Average inventory x Carrying cost/unit
= 120 x 25
= P 3,000

Page 2
Total ordering cost=No. of orders x ordering cost
=15 x 200
=P 3,000
