    Answer:

    The length of chain she is allowed is 1.169 ft

    Explanation:

    The given parameters are;

    The linear density of the chain = 0.83 lb/ft

    The weight limit of the chain she wants = 1.4 lb

    The formula for linear density = Weight/length

    Therefore, in order to keep the chain below 1.4 lb, we have;

    Linear density = Weight/length

    Therefore;

    The maximum length she wants = Weight/(Linear density)

    Which gives;

    The maximum length she wants = 1.4 lb/(0.83 lb/ft) =1.169 ft

    Therefore;

    The length of chain she is allowed = 1.169 ft.
