The local student chapter of IISE decides to hold a bake sale on Frenger Mall. They are selling a traditional, old-world pastry that members can bake at home and bring in. They discover through a study that demand is distributed N(100, 15). Each pastry costs $0.25 to produce and sells that day for $2.00. If they dont sell all the pastries, each unsold pastry is donated at a revenue per item of $0.00. They estimate that a lost sale costs them the lost $1.75 revenue over the $0.25 to make the pastries. Make a recommendation to this group for an optimal strategy.
