This is an exponential growth problem: #A_0r^t#

For this problem the initial population #A_0=5#

The rate of growth #r=2#

The time factor is based on a duration of 115 minutes:

#t=345/115=3# durations

Insert the values into the growth equation:

#A_0r^t#

#5(2)^3=5xx8=40# bacteria 345 minutes from now

Hope that helped
