    Assignment:Find the solution set of inequality 40[90(1+a%)]+32[80(1-0.4a%)] ≤6804 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        40 * ( 90 * ( 1 + a % ) ) + 32 * ( 80 * ( 1 - 0.4 * a % ) ) ≤6804         (1)

---

    From inequality(1)：
         a ≤ 25

---

    The final solution set is :
         a ≤ 25
