Mr. burks had cancer. The cancer cells in his body started out with 8, and they increased at a rate of 200% per day. How many cancer cells were in his body after 5 days? 10 days? 15 days?

So the amount of cancer cells = 8 • 2^x  because this is an exponential growth problem where y=ab^x. Therefore you would plug in your values of A and B with A being your 8 because you start off with 8 cancer cells when you have no days where it increases by 200% and b being 2 because it increases by 200% and that would 2 because the powers of 2 increase by 200% every time.  So, After 5 days there would be 256, after 10 days there would be 8192, and after 15 days there would be 262144.                 

I hope that you find this helpful.
