Question 6.
An electrical engineering company is designing two types of solar panel systems: Standard Panels (S) and High-Efficiency Panels (H). The company has certain constraints regarding the hours of labor and material available for production each week.
Each Standard Panel requires 4 hours of labor and 2 units of material and each High-Efficiency Panel requires 3 hours of labor and 5 units of material.
The company has a maximum of 60 hours of labor and 40 units of material available per week.
The profit from each Standard Panel is GH¢80, and the profit from each High-Efficiency Panel is GH¢100. The company wants to determine how many of each type of panel to produce in order to maximize profit.
i) Solve this LPP by using graphical analysis
ii) What will be the slack at the optimal solution point? Show calculation.
