You are a vendor selling programs in front of the stadium of a certain pro football team that has not had a playoff win in over 10000 days. You have the chance to buy programs from the printer for $0.45 a copy, that you will in turn resell for $1.40. The demand distribution is expected to be normal with a mean = 340 and standard deviation = 68. After the game, any leftover copies will be worthless (nobody will want to remember the game). How many programs should you buy?
