6 The daily demand for six-packs of Coke at Mr. D’s follows a normal distribution, with a mean of 120 and a standard deviation of 30. Every Monday, the delivery driver delivers Coke to Mr. D’s. If the store wants to have only a 1% chance of running out of Coke by the end of the week, how many six-packs should be ordered for the week?

(Assume that orders can be placed Sunday at midnight.)
