    Assignment:Find the solution set of inequality 240.898 >(250.4a+3200)/(a+25) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        240.898 > ( 250.4 * a + 3200 ) / ( a + 25 )         (1)
        From the definition field of divisor
         x + 25 ≠ 0        (2 )

---

    From inequality(1)：
         a ＞ -25
    From inequality(2)：
         a < -25 或  a ＞ -25

---

    From inequalities (1) and (2)
         a ＞ -25    (3)

---

    The final solution set is :
         a ＞ -25
