Question

⦁ Suppose that the number of bacteria in a dish increases by 50% every four hours. There are 64 bacteria initially. Write a function that describes the number of bacteria after t hours have passed. Use your function to find out how many bacteria there will be after 100 hours.

Answer 1

Number of bacteria = 64•(1.5^(t/4))
So after t=100 hours,
64•(1.5^25) = 1,616,075 or 1.616x10^6
