    Assignment:Find the solution set of inequality 960-10k >16.5×sqrtk .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        960 - 10 * k >16.5 × sqrt k         (1)
        From the definition field of √
        x ≥ 0        (2 )

---

    From inequality(1)：
         k < 81.137409
    From inequality(2)：
         k ≥ 0

---

    From inequalities (1) and (2)
         0 ≤ k < 81.137409    (3)

---

    The final solution set is :
         0 ≤ k < 81.137409
