Let's say that at time equals zero, the population is equal to 100 insects or whatever we're measuring the population of. And let's say that at time equals, let's say at time equals 50, the population, so after 50 days, the population is 200. So notice it doubled after 50 days. So given this information, can we solve for C and K? And I encourage you to pause the video and try to work through it on your own. So this first initial condition is pretty straightforward to use because when T is equal to zero, P is 100. So we could say, let's just use, so based on this first piece of information, we could say that 100 must be equal to C, C times E, times E, to the K times zero.
