[ 1/2Inequality]
    Assignment:Find the solution set of inequality 20x＋50（10－x） ≤350 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        20 * x + 50 * ( 10 - x ) ≤350         (1)

---

    From inequality(1)：
         x ≥ 5

---

    The final solution set is :
         x ≥ 5
[ 2/2Inequality]
    Assignment:Find the solution set of inequality 20x＋50（10－x） ≥300 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        20 * x + 50 * ( 10 - x ) ≥300         (1)

---

    From inequality(1)：
         x ≤ 20/3

---

    The final solution set is :
         x ≤ 20/3
