Cynthia Knott's oyster bar buys fresh Louisiana oysters for $4 per pound and sells them for $10 per pound. Any oysters not sold that day are sold to her cousin, who has a nearby grocery store, for $3 per pound. Cynthia believes that demand follows the normal distribution, with a mean of 100 pounds and a standard deviation of 18 pounds. How many pounds should she order each day? Refer to the standard normal table for z-values. Cynthia should order pounds of oysters each day (round your response to one decimal place). Standard Normal Table The table below shows the total area under the normal curve for a point that is Z standard deviations to the right of the mean.
