Asked by Jane
                Suppose that the amount of algae is a pond doubles every 3 hours.  If the pond initially contains 70 pounds of algae, how much algae will be in the pond after 9 hours?
Is the answer 560? I was not sure how to set it up, but doubled it every 3 hours. If this is not correct, please show me how to solve.

    population p = 70*2^(n/3) after n hours
70 * 2^3 = 70*8 = 560
    
70 * 2^3 = 70*8 = 560
