I think you might want to ask this in Biology....
I'll take a look anyways.

anonymous · Answer

y=100 + 2^t

$$y=(100)\times(2)^t$$

y=2^t

$$y=(200) \times (2)^t$$

anonymous · Answer

these are the choices

anonymous · Answer

Option B without a doubt.

anonymous · Answer

so how do we solve this? or at least figure out the answer?

anonymous · Answer

What I did was that I took the basic equation to be A(x^m)
From that one skeletal equation I just took the values.

anonymous · Answer

wait so what do you mean by plugging in the values?

anonymous · Answer

Yes. It's pretty much similar to the question you previously asked (first order reaction)

anonymous · Answer

umm?

anonymous · Answer

is there like an equation that you can show me how to set up?

anonymous · Answer

whats the formula again?
