[ 1/1Inequality]
    Assignment:Find the solution set of inequality （7.14/（0.5A-0.03））+(26/(0.5A-0.055)) ≤1600 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 7.14 / ( 0.5 * A - 0.03 ) ) + ( 26 / ( 0.5 * A - 0.055 ) ) ≤1600         (1)
        From the definition field of divisor
         0.5 * x - 0.03 ≠ 0        (2 )
        From the definition field of divisor
         0.5 * x - 0.055 ≠ 0        (3 )

---

    From inequality(1)：
         A ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         A < 3/50 或  A ＞ 3/50
    From inequality(3)：
         A < 11/100 或  A ＞ 11/100

---

    From inequalities (1) and (2)
         A < 3/50 或  A ＞ 3/50    (4)
    From inequalities (3) and (4)
         A < 3/50 或  3/50 < A < 11/100 或  A ＞ 11/100    (5)

---

    The final solution set is :
         A < 3/50 或  3/50 < A < 11/100 或  A ＞ 11/100
