Prompt

The number of bacteria in a liquid medium doubles every day. There are 83,000 bacteria in the liquid medium at the start of an observation. Which of the following represents the number of bacteria,

y

, in the liquid medium

t

days after the start of the observation?

y = \frac{1}{2} (83, 000)^{t}

y = 2 (83, 000)^{t}

y = 83, 000 (\frac{1}{2})^{t}

y = 83, 000 (2)^{t}
