The first step to solve this equation is placing everything with the exponential to one side of the equality, and everything without the exponential to the other side. So
We already have this, so the first part is ok.
Now, the ln is the interse operation to the exponential, so we apply the ln to both sides of the equality.
If multiply 17000 by 4% or 0.04 you get 680, this is how mucb it grows by each year, multiply 680 by 5 you get 3400, add that to 17000 and that is how much it grows by each year
