Answer 1

a. 208.57 units

b. 104.29 units

Step-by-step explanation:

a. The computation of the economic order quantity is shown below:

`= \sqrt{\frac{2* \text{Annual demand}* \text{Ordering cost}}{\text{Carrying cost}}}`

`= \sqrt{\frac{2* \text{6,000}* \text{\$29}}{\text{\$8}}}`

= 208.57 units

b. And, the average inventory is

= Economic order quantity ÷ 2

= 208.57 units ÷ 2

= 104.29 units

We simply applied the above formulas for calculation of the economic order quantity and the average inventory and the same is shown above
