Algebra 2T.12 Exponential growth and decay: word problems TYQQuesansThere is a population of 30 bacteria in a colony. If the number of bacteria doubles every 330hours, what will the population be 660 hours from now?bacteriaelapSubmit00Smartout of 1oWork it outNot feeling ready yet? This can help:Describe linear and exponential Growth and decay

Answer 1

Ao = initial population = 30

rate of growth = r = 2

time = 660/330 = 2

growth equation:

A0 r^t

Replacing:

30 (2)^2 = 120 baterias
