    Assignment:Find the solution set of inequality 2500m+3000(30－m) ≤80000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        2500 * m + 3000 * ( 30 - m ) ≤80000         (1)

---

    From inequality(1)：
         m ≥ 20

---

    The final solution set is :
         m ≥ 20
