Problema Solution
A certain strain of bacteria that is growing on your kitchen counter doubles every 15 minutes. Assuming that you start with only one bacterium, how many bacteria could be present at the end of 7 hours?
Answer provided by our tutors
every hour there is 4 sets of 15 thus you have 7times 4 periods of duplication. 28.....and after your first doubling period you would have 2 bacteria....and thus
[(total bacteria at first doubling period) to the exponent of (THE # of PERIODS)]
2^28 = 268,435,456
