E to the natural log of 1,100, that is 1,100. The natural log of 1,100 is a power that you raise e to to get to 1,100. So if you raise e to that power, you get 1,100. So that is 1,100. So we get W minus 300 is equal to 1,100, 1,100 e to the t over 25. And then you just add 300 to both sides. W is equal to 1,100 e to the t over 25 plus 300.
