The Lady with the Plan needs to make campaign T-shirt to fund raise. She is trying to decide how many to make for the coming political campaign. During the campaign itself, which lasts one month, a T-shirt sells for $20. Though, when the campaign ends, any unsold T-shirts are sold for $4 apiece. It costs $8 to make a campaign T-shirt. The Lady's calculates of the season's demand of T-shirts is as follows:
Demand Probability
300 0.05
400 0.10
500 0.40
600 0.30
700 0.10
800 0.05
How many T-shirts should the lady stock for the upcoming campaign?
