    SOLUTION This solution is FREE courtesy of BrainMass!

    <br>we Have,
    <br>
    <br>S = 2300*(5t + 1)/(2t + 5}
    <br>
    <br>Taking the derivative with respect to t,
    <br>
    <br>dS/dt = (11500)/(5 + 2t) - [4600 *(1 + 5t)](5+ 2t)^2
    <br>
    <br>
    <br>
    <br>Now substituting t = 9, we get,
    <br>
    <br>dS/dt = (11500)/(5 + 2*9) - [4600 *(1 + 5*9)](5+ 2*9)^2
    <br>
    <br>
    <br>dS/dt = 100
    <br>
    <br>hence answer is d
    <br>
