    Assignment:Find the solution set of inequality 1800 ≥80（20－x）＋110x .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1800 ≥80 * ( 20 - x ) + 110 * x         (1)

---

    From inequality(1)：
         x ≤ 20/3

---

    The final solution set is :
         x ≤ 20/3
