Cynthia Knott's oyster bar buys fresh Louisiana oysters for $$4$ per pound and sells them for $$8$ per pound. Any oysters not sold that day are sold to her cousin, who has a nearby grocery store, for $$2$ per pound. Cynthia believes that demand follows the normal distribution, with a mean of $100$ pounds and a standard deviation of $19$ pounds. How many pounds should she order each day? Refer to the standard normal table for $z-$values.
