    Assignment:Find the solution set of inequality (32000-60a-60a)/120 >= 90+a .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 32000 - 60 * a - 60 * a ) / 120 >= 90 + a         (1)

---

    From inequality(1)：
         a ≤ 265/3

---

    The final solution set is :
         a ≤ 265/3
