Explanation:
Incremental Costs would be considered here to evaluate which safety stock level is the best for the company.
The working is as under:
<u>Safety Stock</u>  <u>Carrying Cost</u>      <u>Stock-out Cost</u>                    <u>Total Cost</u>
    0                        0                     (100*0.2 + 200*0.2) * 80         4,800
  100                100*30 = $3000   (100 * 0.2) * 80                        1,600
 200               200*30 = $6000   (200 * 0.2) * 80                       3,200
The total cost has started growing as the safety starts growing above the 100 units level. This means that the safety stock must be 100 units as the cost at this level is the lowest to the company.
