    Step-by-step explanation:

    The question is about growth function and you are asked to find out the growth rate. Growth function has a format of

    y = a (1+r) ^t

    Where

    y = future value = S (t)

    a = current value = 273

    r = growth rate

    t = time = t

    Since its a growing function, the r will be positive. If its decay function then the r will be negative. As you can see, the growth rate value is located inside the parentheses. The growth rate of the function should be:

    (1+r) = (1.073)

    r = 1.073 - 1

    r = 0.073
