Ascientist running an experiment starts with 100 bacteria cells. these bacteria double their population every 15 hours.  find how long it takes for the bacteria cells to increase to 300. use the formula , where   is the original number of bacteria cells,   is the number after  t  hours,  and  d  is the time taken to double the number.

it takes 24 hours for the bacteria cells to increase to 300

Step-by-step explanation:

WE use the formula

Where A is the initial amount of bacteria= 100

bacteria doubles every 15 hours so b=2

d= 15 because d is the time taken to double the number

t is the number of hours

c is the number of bacteria after t hours = 300

Plug in all the values and solve for 't'

Divide both sides by 100

Now we take log on both sides

As per log property we can move the exponent before log

log a^m = m log(a)

Divide both sides by log(2)

Multiply both sides by 15

t = 23.77

So its approximately 24 hours

your answer would be 12

answer: c. is your answer
