if a certain type of bacteria quadruples every 15 minutes, how many bacteria will be presents after 90 minutes if the initial population was 5 bacteria?
For this case we have an equation of the form: y = A (b) ^ (t / n) Where, A: initial amount b: growth rate t: time n: number of time periods Substituting values we have: y = 5 * (4) ^ (90/15) y = 20480 Answer: will be presents after 90 minutes about: y = 20480 bacteria
