I liked how you clearly explained each step in setting up and solving. Breaking it down into finding the general solution first, and then plugging in the initial values to get the particular solution made it easy to follow.
My only question is in the last step when solving for t – why did you write ln(100) = 2ln(10)? I’m not sure where the 2ln(10) came from. Overall though, the solution looks solid!
Thanks so much for your feedback! $ln(100)=2ln(10)$ is actually just a logarithmic property. We used it there so we can cancel out the $ln(10)$ on both sides of the equal sign in the next step.
