Answer:
Option d (501-600) is the correct answer.
Step-by-step explanation:
Given:
Unit sales,
= 20,000
Ordering costs,
= $20
Carrying costs,
= $1
Safety stocks,
= 100
Now,
The EOQ will be:
=

By putting the values, we get
=

=

=

hence,
The average inventory will be:
=
![[Safety \ stock +((EOQ)/(2) )]](https://img.qammunity.org/2022/formulas/business/college/r94i91ciugn430wqcy3h1f96uhr2tn3xhp.png)
=
![[100+((894.43)/(2) )]](https://img.qammunity.org/2022/formulas/business/college/usuqj35zaxb06rkezoy56pu84agam3kkau.png)
=
![[100+447.21]](https://img.qammunity.org/2022/formulas/business/college/5x1k8h4opw0yt7csuejnasmz54h168vwxd.png)
=
(lies between 501-600)
Thus the above is the correct response.
