    Answer: x\in [53,\infty)

    Step-by-step explanation:

    Given

    Ade doubles her number and subtract 5 from it. The result cannot be less than 100

    Suppose the number is x

    According to the question

    \Rightarrow 2x-5\geq100\\\text{Solve the inequality}\\\Rightarrow 2x\geq105\\\Rightarrow x\geq52.5\\\text{for integer number, the range is given by }\\\Rightarrow x\in [53,\infty)
