[ 1/1Inequality]
    Assignment:Find the solution set of inequality 3*2^(x-3)*(10-x) ≥(3*2^(x-3)-1)*9 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        3 * 2 ^ ( x - 3 ) * ( 10 - x ) ≥ ( 3 * 2 ^ ( x - 3 ) - 1 ) * 9         (1)

---

    From inequality(1)：
         x ≤ 3.351426

---

    The final solution set is :
         x ≤ 3.351426
