    Assignment:Find the solution set of inequality {0.92x+0.98（900-x）}÷900 ≥0.94 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 0.92 * x + 0.98 * ( 900 - x ) ) ÷ 900 ≥0.94         (1)

---

    From inequality(1)：
         x ≤ 600

---

    The final solution set is :
         x ≤ 600
