This is, well, let me not cross this. This right over here is an expression for G of T. It was indeed a separable differential equation. It took a little bit of algebraic manipulation to get us there, but we were able to do it, and we were not only able to solve for the general solution. We were able to find the particular solution using this initial condition right over here, that G of zero is equal to 91. Now we'll do the easy part. Based on this model, what is the internal temperature of the potato at time T equals three? So G of three is equal to negative three over three plus four, let me just write it out.
