           ☆2 inequalities

[ 1/2Inequality]
    Assignment:Find the solution set of inequality (1-0.4)X <= (4+0.15)*(24-X) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 - 0.4 ) * X <= ( 4 + 0.15 ) * ( 24 - X )         (1)

---

    From inequality(1)：
         X ≤ 20.968421

---

    The final solution set is :
         X ≤ 20.968421
[ 2/2Inequality]
    Assignment:Find the solution set of inequality (1-0.35)X <= (4+0.15)*(24-X) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 - 0.35 ) * X <= ( 4 + 0.15 ) * ( 24 - X )         (1)

---

    From inequality(1)：
         X ≤ 83/4

---

    The final solution set is :
         X ≤ 83/4
