A market survey indicates that the daily demand for interior paint cannot exceed that for
exterior paint by more than 1 ton. Also, the maximum daily demand for interior paint is 2 tons.
Reddy Mikks wants to determine the optimum (best) product mix of interior and exterior
paints that maximizes the total daily profit.
The LP model, as in any OR model, has three basic components.
1. Decision variables that we seek to determine.
2. Objective (goal) that we need to optimize (maximize or minimize).
3. Constraints that the solution must satisfy.
