Brian wishes to determine the number of copies of The St. John’s Times he should purchase each Sunday. A study of the historical data showed that the demand is approximately normally distributed with mean = 23.45 and standard deviation = 8.71. He purchases the papers for 50 cents and can sell them for $1.00. He can salvage unsold copies for 15 cents.
