The manufacturer of a popular personal computer has orders from two dealers. Dealer D, wants at least 38 computers, and dealer D2 wants at least 20 computers. The manufacturer can fill the orders from either of two warehouses, W, or W2. There are 30 computers on hand at Wy, and 34 at W2. The costs to ship one computer to each dealer from each warehouse are shown to the right. Complete parts (a) and (b). D1 W $6 W2 $5 D2 $10 $9 1 (a) How should the orders be filled to minimize shipping costs? Warehouse W, should ship computer(s) to dealer D, and computer(s) to dealer D. Warehouse W, should ship computer(s) to dealer D and computer(s) to dealer D2. The minimum cost will be s (Simplify your answers.) (b) Find and interpret the values of any nonzero slack or surplus variables List the value(s) of the nonzero slack variable(s). Select the correct choice and, if necessary, fill in the answer box to complete your choice. O A. The value(s) of the nonzero slack variables is(are) (Use a comma to separate answers as needed.) OB. There are no nonzero stack variables What does the value of a nonzero slack variable represent in this problem? O A. The value represents the number of computers in a warehouse that are not shipped. OB. The value represents the number of computers that a warehouse ships. OC. The value represents the excess number of computers that a dealer receives OD. There are no nonzero slack variables. List the value(s) of the nonzero surplus variable(s). Select the correct choice and, if necessary, fill in the answer box to complete your choice O A. The value(s) of the nonzero surplus variables is(are) (Use a comma to separate answers as needed) B. There are no nonzero surplus variables What does the value of a nonzero surplus variable represent in this problem? O A. The value represents the number of computers that a dealer receives. OB. The value represents the number of computers in a warehouse that are not shipped. O C. The value represents the number of computers that a warehouse ships. OD. There are no nonzero surplus variables
