[ 1/1Inequality]
    Assignment:Find the solution set of inequality （2.2－2）（6000－y）＋（3.3-2.8） ≥1800 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 2.2 - 2 ) * ( 6000 - y ) + ( 3.3 - 2.8 ) ≥1800         (1)

---

    From inequality(1)：
         y ≤ -5995/2

---

    The final solution set is :
         y ≤ -5995/2
