Expert Solution & Answer
Chapter 5, Problem 1RP
a.
Explanation of Solution
Profit
- Let
- The new optimum solution value or profit is calculated by the given formula:
- The key row value can be calculated by the given formula:
- From the LINDO output, here the old optimum value is 1,360,000.
- Hence the new value is:
b.
Explanation of Solution
Increasing capacity
“Yes”, HAL should hire the contractor if the capacity is increased to 850 computers at a cost of 5000.
Reason
- From the LINDO output, the dual price in row 2 is 133.333.
- When the capacity is increased to 850 computers, then the profit should be increased by 850(133.333).
- This means the profit value should be greater than 5000.
- Hence the capacity should be increased and here the allowable increase is 100.
- Hence HAL should hire the contractor in order to increase the capacity.
c.
Explanation of Solution
Profit
- The new optimum solution value is calculated by the given formula:
- The key row value can be calculated by the given formula:
- From the LINDO output, the reduced cost for XLV is 33.333.
- Hence the profit of VAX can be increased by 33.333 in order to produce VAXes in Los Angeles.
d.
Explanation of Solution
Extra labour cost
- Let
- Here the labour is purchased at a cost of 20 per hour.
- Here the Key value is 313.333.
- Hence the

1. Create a Vehicle.java file. Implement the public Vehicle and Car classes in Vehicle.java, including all the variables and methods in the UMLS.
Vehicle
-
make: String
model: String
-year: int
+ Vehicle(String make, String, model, int, year)
+ getMake(): String
+ setMake(String make): void
+ getModel(): String
+ setModel(String model): void
+ getYear(): int
+ set Year(int year): void
+toString(): String
Car
- numDoors: int
+ numberOfCar: int
+ Car(String make, String, model, int, year, int numDoors)
+ getNumDoors(): int
+ setNumDoors (int num Doors): void
+ toString(): String
2. Create a CarTest.java file. Implement a public CarTest class with a main method. In the main method, create one Car object and print the object using
System.out.println(). Then, print the numberOfCar.
Your printing result must follow the example output:
make Toyota, model=Camry, year=2022 numDoors=4
1
Hint: You need to modify the toString methods in the Car class and Vehicle class!
