Question

A bacteria population is tripling every hour. By what factor does the population change in 1/2 hour? Select all that apply.

Answer 1

B but there might be more, look below. I didn't have time to calculate the other answers.

Explanation:

Well, it is growing x3 each hour, so each half hour it's 1.5...

So whichever is equal to 1.5 is the answer, like B. There might be more.
