    Assignment:Find the solution set of inequality -10x²+1500x－50000 ≥4000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -10 * x ^ 2 + 1500 * x - 50000 ≥4000         (1)

---

    From inequality(1)：
         60 ≤ x ≤ 90

---

    The final solution set is :
         60 ≤ x ≤ 90
