Samatya supermarket is planning to order souvenir cups for the upcoming national feast. The cups cost $5 and sells for $20 each. The managers believe that the demand will be 500 cups with 20% probability, 1000 cups with 50% probability and 1500 cups with 30% probability. They plan to order 600, 1000 or 1300 cups. They have the opportunity to order 200 cups more for with a $15 per cup cost if the demand comes out as 1500 cups. The cups left on hand will be scrapped as there will be no more demand for them. Draw and solve the decision tree for this problem.
