    Assignment:Find the solution set of inequality 112 ≤70×（100-10R）×0.01R .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        112 ≤70 × ( 100 - 10 * R ) × 0.01 * R         (1)

---

    From inequality(1)：
         2 ≤ R ≤ 8

---

    The final solution set is :
         2 ≤ R ≤ 8
