Expert Solution & Answer
Chapter 5.2, Problem 2P
a.
Explanation of Solution
Optimum solution
- In this case the reduced cost for
- The allowable increase for
- Hence the basic variables remains the same
b.
Explanation of Solution
Shadow price
- The Relevant Shadow Price is ‑$20.
- If demand is decreased by up to 3 cars then the current basis remains optimal.
- So Dual Price may be used to compute new z‑value.

- Java Graphics (Bonus In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels.
