1. Explain the primary differences between a software package such as QM for Windows and Excel spreadsheets for solving linear programming problems.

2. Find the optimal solution of the following linear programming problem using QM for Windows or Excel.

Minimize 2x + 2y

Subject to

x + y > 5

x + 2y < 8

x, y > 0

3. Write the following problem in the required format for QM for Windows. Do NOT solve the problem.

Maximize 4x + 5y

Subject to

4. Southern Sporting Goods Company makes basketballs and footballs. Each product is produced from two resources—rubber and leather. The resource requirements for each product and the total resources available are as follows:

Resource Requirements per Unit

Product Rubber (lb.) Leather (ft.2)

Basketball 3 4

Football 2 5

Total resources available 500 lb. 800 ft.2

Each basketball produced results in a profit of $12, and each football earns $16 in profit.

I have formulated and solved the problem by using QM for Windows. The output from QM for Windows is displayed below.

Linear Programming Results:

Basketball Football RHS Dual

Maximize 12 16

Rubber 3 2 <= 500 0

Leather 4 5 <= 800 3.2
