    Assignment:Find the solution set of inequality 0 <(10400-150x)/100X+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 inequality(1)：
         -0.028834 < x < 69.362167
    From inequality(2)：
         x < 0.260595 或  x ＞ 69.072738

---

    From inequalities (1) and (2)
         -0.028834 < x < 0.260595 或  69.072738 < x < 69.362167     (3)

---

    The final solution set is :
         -0.028834 < x < 0.260595 或  69.072738 < x < 69.362167
