The grаdes will be given based on necessary steps (10 points) Please formulate a linear programming for the network of a transshipment problem below. The values under the nodes are supply amount (negative value) or demand amount (positive value); the values above the arcs are the shipping costs. (8 points) A company prints a Christmas card once a year and distributes the cards to and gift shops in the United States. It costs 50 cents to print each card, and the company receives 65 cents for each card sold. Because the cards have the current year printed on them, those cards that are not sold are generally discarded. Based on past experience and forecasts of current buying patterns, the probability distribution of the number of cards to be sold nationwide for the next Christmas season is estimated to be Quantity sold Probability 100,000–150,000 0.10 150,001–200,000 0.15 200,001–250,000 0.25 250,001–300,000 0.20 300,001–350,000 0.15 350,001–400,000 0.10 400,001–450,000 0.05 Determine the number of cards that company should print this year.
