    Assignment:Find the solution set of inequality （50-x）（300+300x） ≥26250 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 50 - x ) * ( 300 + 300 * x ) ≥26250         (1)

---

    From inequality(1)：
         0.777648 ≤ x ≤ 48.222352

---

    The final solution set is :
         0.777648 ≤ x ≤ 48.222352
