So this is just the same thing as C times one. And just like that, we have figured out what C is. So now we can write, we can now write that the population is going to be equal to 100, E to the KT. And so you can see, expressed this way, our C is always going to be our initial population. So E to the KT, E to the KT. And now we can use the second piece of information. So our population is 200.
