Unformatted text preview: Monday, October 25, 2010 Notes Team #1 Isa Cruz, Huan Guo, Katie Ramp, Michelle Leahy, Alli Zheng Hotel reservations re-cap: Important points Different people are willing to pay different prices. To increase profits, reserve rooms for those willing to pay higher prices. Prob( y g3410 D) = g3004g3048 g3004g3048g2878g3004g3042 Reserve Y for customers willing to pay the full price, Pf = $225 Reserve D for customer willing to pay the discount price, Pd = $159 Example barb2right Pf = $500 Pd = $200 400 rooms P( X = x) = g1857 g2879g3090 g3090 g3299 g3051!
