[ 1/1Inequality]
    Assignment:Find the solution set of inequality [(16.4+2t)*(135.69+7.8t)/(15.4+t)]/95 >= 1.8 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( ( 16.4 + 2 * t ) * ( 135.69 + 7.8 * t ) / ( 15.4 + t ) ) / 95 >= 1.8         (1)
        From the definition field of divisor
         15.4 + x ≠ 0        (2 )

---

    From inequality(1)：
         -16.244918 ≤ t ≤ -15.4 或  t ≥ 1.610302
    From inequality(2)：
         t < -77/5 或  t ＞ -77/5

---

    From inequalities (1) and (2)
         -16.244918 ≤ t < -77/5 或  t ≥ 1.610302    (3)

---

    The final solution set is :
         -16.244918 ≤ t < -77/5 或  t ≥ 1.610302
