AnnyKZ [126]

Solution :

It is given that :

$f'(t) = (350 \ln   t)'$

       $=350(\ln t)'$

        $=\frac{350}{t}$

So, f(5)=350 \ln (5) \approx 563

     $f'(5) = \frac{350}{5}$

              =70

The relative change is then,

$\frac{f'(5)}{f(5)}=\frac{70}{350\ \ln(5)}$

         $=\frac{1}{5\ \ln(5)}$

         $\approx 0.12$

          =12\%

This means that after 5 weeks, the revenue from the DVD sales in $563 with a rate of change of $70 per week and the increasing at a continuous rate of 12% per week.
