[ 1/1Inequality]
    Assignment:Find the solution set of inequality （200+18.25*0.8b）/b ≤178 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 200 + 18.25 * 0.8 * b ) / b ≤178         (1)
        From the definition field of divisor
        x ≠ 0        (2 )

---

    From inequality(1)：
         b ≤ 0 或  b ≥ 1.22399
    From inequality(2)：
         b < 0 或  b ＞ 0

---

    From inequalities (1) and (2)
         b < 0 或  b ≥ 1.22399    (3)

---

    The final solution set is :
         b < 0 或  b ≥ 1.22399
