[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0 ≤3-2x/5 ≤1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0 ≤3 - 2 * x / 5         (1)
        3 - 2 * x / 5 ≤1         (2)

---

    From inequality(1)：
         x ≤ 15/2
    From inequality(2)：
         x ≥ 5

---

    From inequalities (1) and (2)
         5 ≤ x ≤ 15/2    (3)

---

    The final solution set is :
         5 ≤ x ≤ 15/2
