    Assignment:Find the solution set of inequality 8.5a+3[1-(1/12+1/20)a] ≤65 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        8.5 * a + 3 * ( 1 - ( 1 / 12 + 1 / 20 ) * a ) ≤65         (1)

---

    From inequality(1)：
         a ≤ 7.654321

---

    The final solution set is :
         a ≤ 7.654321
