    Assignment:Find the solution set of inequality 5000+70%*（95%*100*x+5%*120*x） ≥12000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        5000 + 70 % * ( 95 % * 100 * x + 5 % * 120 * x ) ≥12000         (1)

---

    From inequality(1)：
         x ≥ 99.009901

---

    The final solution set is :
         x ≥ 99.009901
