Linear Inequalities

Concept:Formulate linear inequalities for given resource constraints.Explanation:Let $x$ be number of model A scooters, $y$ be number of model B scooters.Assembly: $15x + 6y \le 300$ (available 300 man-hours).Painting and finishing: $5x + 4y \le 120$ (available 120 man-hours).Checking and testing: $1x + 2y \le 50$ (available 50 man-hours).Non-negativity: $x \ge 0$, $y \ge 0$.These inequalities match option A.Answer:Option A is correct.
