Solution through graphical method.
Two model of a product - Regular (X) and Deluxe (Y) - are produced by a company linear programming model is used to determine the production schedule.
Maximize profit subject to:
50 X + 60Y
8X + 10Y ≤ 900 (labor hours)
X + Y ≤120 (total units demanded)
4X + 10 Y ≤500 (raw material)
X, Y ≥ 0
The optimal solution is X = 100, Y = 0.

2. The second constraint.
3. The third constraint.
4. All of these.
5. None of these.
