    Assignment:Find the solution set of inequality 0 <(10400-150x)/100/X+3 <30 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0 < ( 10400 - 150 * x ) / 100 / x + 3         (1)
         ( 10400 - 150 * x ) / 100 / x + 3 <30         (2)
        From the definition field of divisor
        x ≠ 0        (3 )

---

    From inequality(1)：
         x < -208/3 或  x ＞ 0
    From inequality(2)：
         x < 0 或  x ＞ 3.649123
    From inequality(3)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         x < -208/3 或  x ＞ 3.649123    (4)
    From inequalities (3) and (4)
         x < -208/3 或  x ＞ 3.649123    (5)

---

    The final solution set is :
         x < -208/3 或  x ＞ 3.649123
