    Assignment:Find the solution set of inequality 16 <10+1.2(a-5) <17.2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        16 <10 + 1.2 * ( a - 5 )         (1)
        10 + 1.2 * ( a - 5 ) <17.2         (2)

---

    From inequality(1)：
         a ＞ 10
    From inequality(2)：
         a < 11

---

    From inequalities (1) and (2)
         10 < a < 11     (3)

---

    The final solution set is :
         10 < a < 11
