Question

The population of bacteria in an

experiment has been increasing by 70%
each day. If there were 100 bacteria at
the beginning of the experiment, predict
the number of bacteria in 3 days.

Answer 1

491.30 bacteria

Explanation:

70% per day

day 1) 100 bacteria × 70% = 170 bacteria

day 2) 170 bacteria × 70% = 289 bacteria

day 3) 289 bacteria × 70% = 491.30 bacteria
