A company wants to determine its reorder point $($ROP$).$ Demand is variable and they want to build a safety stock into ROP. If the average daily demand is $11,$ the lead time is $4$ days, the desired z$-$value is $1\mathrm{.}96,$ and the standard deviation of usage during a single day is $2\mathrm{.}54,$ what is the desired value of ROP?
