C. 130%
D. 300%

Sagot :

THE ANSWER IS THE D!!!!!!!!!!!!

Answer:

Option D. 300%

Step-by-step explanation:

Let the number of bacteria in Dr Nall's petri dish = x

After one hour number of bacteria in the petri dish = 3x

So the percentage of the population compared to the population the hour before will be

= [tex]\frac{\text{Population after 1 hour}}{\text{Population before 1 hour}}\times 100[/tex]

= [tex]\frac{3x}{x}\times 100[/tex]

= 300%

Therefore, Option D. will be the answer.
