<h2>Hello!</h2>

The answer is:

The correct option is A. 8.3.

<h2>Why?</h2>

To calculate the number of weeks that will pass, we need to use the given information.From the statement we know that we need to use the value of $600 substituting it as "y", and then, isolate "x", so, calculating we have:

log(y)=0.30x+0.296\\\\log(600)=0.30x+0.296\\\\2.78=0.30x+0.296\\\\2.78-0.296=0.30x\\\\x=\frac{2.78-0.296}{0.30}=8.28=8.3

Hence, the correct option is A. 8.3.

Have a nice day!
