The daily demand for six-packs of Coke at Mr. D’s supermarket follows a normal distribution with mean 120 and standard deviation 30. Every Monday the Coke delivery driver delivers Coke to Mr. D’s. If Mr. D’s wants to have only a 1% chance of running out of Coke by the end of the week, how many should Mr. D’s order for the week? Assume orders are placed on Sunday at midnight.
