[ 1/2Inequality]
    Assignment:Find the solution set of inequality 45a+8-3/2a ≥240 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        45 * a + 8 - 3 / 2 * a ≥240         (1)

---

    From inequality(1)：
         a ≥ 16/3

---

    The final solution set is :
         a ≥ 16/3
