# Chapter 6 Cost Acctg. (De Leon)

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

= 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
