Determine the reorder point to achieve a desired service level of $96\%.$ Daily demand $($d$)$ is $12$ units a day. Standard deviation in demand $(\backslash$sigma d

$)$ is $2$ units a day. Lead time $($LT$)$ averages $4$ days, with a standard deviation in lead time $(\backslash$sigma LT

$)$ of $1$ day.
