    Assignment:Find the solution set of inequality 150a+120÷50×(3000-75a) ≤6350 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        150 * a + 120 ÷ 50 × ( 3000 - 75 * a ) ≤6350         (1)

---

    From inequality(1)：
         a ≥ 85/3

---

    The final solution set is :
