    Assignment:Find the solution set of inequality （16-10）×200×（1-20%）+200×（x－30） ≥3200×90% .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 16 - 10 ) × 200 × ( 1 - 20 % ) + 200 × ( x - 30 ) ≥3200 × 90 %         (1)

---

    From inequality(1)：
         x ≥ 198/5

---

    The final solution set is :
         x ≥ 198/5
