    Assignment:Find the solution set of inequality 200(1-25%)+200y-8000 ≥3000×70% .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        200 * ( 1 - 25 % ) + 200 * y - 8000 ≥3000 × 70 %         (1)

---

    From inequality(1)：
         y ≥ 199/4

---

    The final solution set is :
         y ≥ 199/4
