[ 1/1Inequality]
    Assignment:Find the solution set of inequality (449.093-x)*(667.79-600)-(x-427.293)*(1146.4-667.79) >= 0.013*(1146.4-667.79)*(667.79-600) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 449.093 - x ) * ( 667.79 - 600 ) - ( x - 427.293 ) * ( 1146.4 - 667.79 ) >= 0.013 * ( 1146.4 - 667.79 ) * ( 667.79 - 600 )         (1)

---

    From inequality(1)：
         x ≤ 429.225718

---

    The final solution set is :
         x ≤ 429.225718
