1. Find a linear program for each of the cases described below. For each case, you must show your problem is correct by solving both the primal linear program and its corresponding dual using the graphical method. (Hint: do not use more than two decision variables and more than two constraints). Please solve all and show work clearly.
a) Primal is unbounded and dual is infeasible.
b) Dual is unbounded and primal is infeasible.
c) Both, primal and dual are infeasible.
d) Both, primal and dual have an optimal solution.
2. Proficient strategy execution
A) is an every-now-and-then task.
B) is always the product of much organizational learning.
C) is achieved unevenly, coming quickly in some areas and more slowly in others.
D) entails accomplishing desired outcomes and then examining what went right and what went wrong.
E) directly involves only the CEO and board of directors of the firm.
3. A particular raw material is available to a company at three different prices, depending on the size of the order
Less than 100 pounds $ 30 per pound
100 pounds to 2,999 pounds $ 29 per pound
3,000 pounds or more $ 28 per pound
The cost to place an order is $30. Annual demand is 2,600 units. Holding (or carrying) cost is 20 percent of the material price.
What is the economic order quantity to buy each time, and its total cost? (Round your answers to the nearest whole number.)
A- Economic order quantity ........ pounds
B- Total cost $.............
