Answer:
18 units
Explanation:
The computation of the economic order quantity is shown below:
= [tex]\sqrt{\frac{2\times \text{Annual demand}\times \text{Ordering cost}}{\text{Carrying cost}}}[/tex]
= [tex]\sqrt{\frac{2\times \text{1,215}\times \text{\$10}}{\text{\$75}}}[/tex]
= 18 units
At 18 units of order size, the total cost would minimize.
It is that level at which the total carrying cost and the total ordering cost is equal.
Total cost = Purchase cost + ordering cost + carrying cost
It is a combination of purchase cost, ordering cost and the carrying cost
