Weekly demand for jeans at a Gap store is normally distributed with a mean of $100$ and a SD of

$50.$ The supply plant takes $3$ weeks to supply a Gap order. The store manager monitors its

inventory continuously and reorders jeans when the available inventory drops below $350.$ How

much safety stock does the store carry? What CSL does the store achieve? If the store manager

wants to achieve a target CSL of $95\%,$ how much safety inventory of jeans should the store carry?

What should its ROP be$?$
