Question 1204360: A bacteria culture initially has 5000, and its size increased by 8% every minute. About how many bacteria are present in the culture after 4 mins.
My answer is initially 6802.44 but this amount of bacteria should only be after around 4 hours and not minutes.

(1) Why would you think your answer should be after 4 hours instead of 4 minutes? The growth rate is given per minute....

(2) The number of bacteria must be a whole number. Since the question asks ABOUT how many bacteria there are after 4 minutes, your answer should be rounded to the nearest whole number.

ANSWER: 6802
