    Assignment:Find the solution set of inequality 75     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        75 < x * 2 + 0.15 * x + 24         (1)
         x * 2 + 0.15 * x + 24 <84         (2)

---

    From inequality(1)：
         x ＞ 23.72093
    From inequality(2)：
         x < √778799351/1000

---

    From inequalities (1) and (2)
         23.72093 < x < √778799351/1000     (3)

---

    The final solution set is :
         23.72093 < x < √778799351/1000
