Question

Caleb started with 50 bacteria for his science experiment and they doubled in one day. Jenna also started with 50 bacteria for her experiment and after one day, her number of bacteria was equal to 50 to the second power. Choose the statement that is true for the number of bacteria after one day.
A Caleb's experiment had 100 bacteria and Jenna's experiment had 250 bacteria.



B Caleb's experiment had 100 bacteria and Jenna's experiment had 2,500 bacteria.



C Caleb's experiment had 500 bacteria and Jenna's experiment had 500 bacteria.



D Caleb's experiment had 250 bacteria and Jenna's experiment had 500 bacteria.

Answer 1

Answer: B

Step-by-step explanation:

The second power basically means that you multiply the number by itself that many times depending on the power, and since it's 50^2, the answer is Caleb - 100 | Jenna - 2,500. (Tip: Just multiply 50 x 50)
