This is the second time posting this question: As a fund-raiser for a student organization, some students have decided to sell individual pizzas outside the Union on Friday. Each pizzas will sell for $1.75 and costs the organization $.77. Historical sales indicated that between 55 and 60 dozen pizzas will be sold with the probability distribution given below:

Dozens of pizzas 55, 56, 57, 58, 59 and 60: Probability: 0.15, 0.20, 0.10, 0.35, 0.15 and 0.05. To maximize the profit contribution, how many pizzas should be ordered?

Assume pizzas must be ordered by dozen. What is the expected value of perfect information in this problem? What is the maximum amount the organization would be willing to pay for perfect information?
