Answer:
There would be 1080 bacteria in the culture.
Step-by-step explanation:
Initial number of bacteria = 40
Given that
culture of bacteria triples by the end of each hour
Number of bacteria after 1 hour = 40*3 (multiplying initial number of bacteria by 3)
Number of bacteria after 1 hour = 120
number of bacteria after 2 hours = 3*Number of bacteria after 1 hour = 3*120
number of bacteria after 2 hours =360
number of bacteria after 3 hours = 3*Number of bacteria after 2 hour = 3*360 = 1080
Thus,
there would be 1080 bacteria in the culture.
